Concreto - Durable Concrete Range

Agile is Self-compacting, self-levelling & free flowing Concrete with self-Placing and consolidating properties, especially developed to make construction easy, eliminate need of compaction, ensure faster construction & less labour dependent.

The workability of Agile is higher than normal concrete, its workability is measured in horizontal spread diameter and is termed as flow (min 600 mm) while in normal concrete workability is measured in terms of slump (30 mm to 200mm).

Agile is having self-compacting properties no vibration is required like normal concrete.

Agile is a self-flowing concrete and gets consolidated by its own weight hence not requiring any compaction.

Agile is designed based on “Granular packing model to achieve desired parameters without adding VMA, therefore there is no segregation in Agile.

VMA is viscosity modifying agent, added in concrete to enhance the viscosity. It is generally added in Self compacting concrete but in Agile VMA is not required.

Agile is conforming to IS 10262 parameters and is designed based on EFNARC (European) guidelines.

• Flow – 600 mm to 850 mm
• Viscosity measured by O funnel or V funnel, having value in the range of 6 to 12 seconds
• L Box test to test passing ability through congested reinforcement. Ratio of H1/H2 should be minimum 0.85
• U Box test to measure filling ability. H1-H2 should be maximum 50 mm
• Segregation resistance test – segregation value should be less than 15 %

Agile is available in M 25 to M 100 Grades

In case of Agile “Flow” is measured in place of Slump. The flow of Agile is more than 600mm at site.

• Applications of Agile are
• Exposed Concrete work
• All types of vertical & Horizontal Applications like Column, Beam, Shear Wall, Slab, Beam, Transfer girder, Retaining wall etc

Setting time & Deshuttering time of Agile is same as that of Standard Concrete and can be customized for high early strength if required.

Shuttering should be designed by hydrostatic pressure, there should be not any gaps in shuttering.

Agile can be used with any type of shuttering, provided the shuttering quality should be good and it should be design as per hydrostatic pressure

There is significant reduction in pores and voids in Agile, but it cannot be claimed as waterproof concrete.

Agile is not having non-shrink properties, there might be some minor surface cracks in Agile. Proper precautions are to be taken to minimise cracks while concreting and finishing.

Agile is a self-compacting and self-flow concrete and it is compacted by its own weight, so it doesn’t require any external vibrator, Minor Surface tamping is suggested in case if vertical members to remove entrapped air.

It varies upon height of pouring, for 1.5 M height the maximum distance can be 3 M.

Minimum thickness of the member is 75mm. Maximum Height of fall is 1.5 m

Generally maximum size of aggregate is 10 MM, but in case of mass concrete we can use up to 20mm

Density – 2300 to 2500 (depending upon raw material specific gravity)

Nuvoco can also supply Agile in TM or Bags as per site requirement so there is no capping for minimum quantity.

Retention can be designed up to 6 Hrs.

Yes, Agile can be supplied with controlled temperature also.

• Agile is having higher durability compared to normal concrete based on following parameters
• RCPT value, Chloride permeability, Water Permeability is lower as compared to Standard concrete

Non-Structural and low-density concrete. It enhances thermal insulation and effectively replaces brickbat coba and concrete Screed thereby reducing dead load on existing structures.

XLite is manufactured under Controlled parameters at Ready-mix plants with required density. Whereas foam concrete it produced at site with help of foaming agents which generally lack accuracy in achieving low density.

XLite is available density in as low density as 800-1800 kg/cum. It can also be customized upto 600 kg/cum.

There are 2 variants of XLite. 1) Xlite 2) XLite Structural Xlite is a nonstructural Concrete due to its low density feature.

XLite Standard is a nonstructural low-density concrete having compressive strength up to 4mpa.
But in the case of XLite Structural, you can get compressive strength up to 25Mpa.
XLite Structural can also be designed for MoE requirement. Density of XLite Structural ranges from 1000 to 1800 kg/m³ for compressive strength of 7.5 Mpa to 25 Mpa.

XLite has better thermal insulation properties than Brick bat coba and requires one day to complete the job as it is easy to place, finish, maintain and repair. Whereas Brick bat coba requires more skilled labor and 6-7 days to place and finish.

Using XLite upto 1000kg/cum can reduce upto 50% dead load of terrace floor.

Low density in XLite Standard and Structural helps in reduction of dead load which facilitates to optimize design cost, better thermal and sound insulation properties.

Yes. XLite Structural can be used in R.C.C. slabs, deck slabs where compressive strength requirement is upto 1800 kg/m³.

Its takes the same time as normal concrete settinging time which is 4 to 5 hrs.

Depending upon the area XLite can be done in one single day even for larger slabs of approximately 15000 sq.ft.

To produce XLite Standrad EPS beads are used in place of aggregates.

For production of XLite Structural LECA aggregates are used.

XLite cannot be left exposed to direct sunlight. It is mandatory to cover XLite with 25-50mm finish layer of tiles/granite/marble.

A minimum of 7 days of curing is required.

For curing XLite, sprinkling of water and applying of curing compound can be used as the best methods. Please don’t use the ponding method for XLite curing.

XLite Structural can be used for replacing Brick bat coba, screed concrete for flooring, Deck slab with reinforcement where low density concrete is required and R.C.C. slabs where compressive strength required is upto 25 Mpa.

No. Nuvoco supplies XLite Standard which can replace brick bat coba

Xlite is available at minimum 600kg/cum and

xlite Structural can be produced at minimum 1000kg/cum

Xlite maximum grade is Mpa 8 with density of 2 to 8mpa strength and XLite Structural is available upto M-25 Grade with density ranging from 1000-1800kg/cum.

Yes. But, Using XLite can help the developer get LEED points for green building certification.

Lightweight concrete can also be used for the construction of partition walls and panel walls in frame structures apart from roof overlay replacing brick bat coba. It can also be used to reduce the dead load on structure, used for reinforced concrete roof slab and can help in slope maintenance.

The main specialties of lightweight concrete are its low density, light weight, thermal insulation properties and thermal conductivity.
Reduction in dead loads making savings in foundations and reinforcement.
Improved thermal properties.
Improved fire resistance.
Savings in transporting and handling precast units on site.

Light weight concrete pouring should be avoided in structural members because the strength of Light weight concrete is upto 2 to 5 Mpa only.
Nuvoco has developed two types of Light weight concrete. 1) XLite standard for nonstructural applications 2) XLite structural for structural applications having compressive strength upto 25Mpa.

Lightweight concrete decks exhibit fewer cracks than their conventional counterparts. Conventional lightweight concrete can offer durability advantages due to reduced cracking tendency.

Crystalline waterproofing technology is a method used to make concrete structures impermeable to water by inducing the formation of crystalline structures within the concrete matrix. The technology relies on the reaction between active chemicals and moisture present in the concrete. Here’s a breakdown of how crystalline waterproofing technology works:

Introduction of Active Chemicals: Crystalline waterproofing agents, typically in the form of a powder or liquid admixture, are introduced into the concrete mix during the mixing process.

Chemical Reaction with Moisture: The active chemicals within the crystalline waterproofing admixture react with the moisture in the concrete and the by-products of the cement hydration process.

Formation of Crystalline Structures: As a result of the chemical reaction, insoluble crystalline structures begin to form throughout the capillary pores and micro-cracks in the concrete. These crystals grow and spread, filling the voids within the concrete.

Blocking Capillaries and Pores: Over time, the crystalline formations continue to grow and interlock, reducing the size of capillary pores and blocking them completely. This process makes the concrete impermeable to water.

Self-Healing Capability: One of the unique features of crystalline waterproofing technology is its self-healing capability. If new cracks develop over time, the active chemicals can react with moisture again, promoting the growth of additional crystals to seal the cracks.

Permanent Water Tightness: The end result is a concrete structure with enhanced durability and permanent water tightness. The crystalline formations act as a barrier, preventing water penetration and protecting the concrete from the detrimental effects of water, such as corrosion of reinforcing steel.

Crystalline Waterproofing is usually supplied as an easy-to-use, dry powder. It is composed of Portland cement, silica sand and special chemicals. These chemicals react with water to cause long, narrow crystals to grow, filling the pores, capillaries and hairline cracks of the concrete mass.
