Concrete is one of the most important building blocks when it comes to creating a solid, strong, and long-lasting building. As much as possible, concrete workability, strength, and water tightness must be achieved by choosing a right concrete admixture to maintain better water-cement ratio. It is well known that the better strength can achieve by reducing water-cement ratio then by increasing cement content of any concrete mix. So, selection of admixture is very important here to improve the concrete mix.

Nirman Chemicals presents concrete admixtures that are ideal for every kind of concrete for High-rise low-rise, residential and non-residential (Commercial and Institution) building to achieve or modify both the fresh and harden concrete properties. It also reduces the cost of building with concrete. Using well-developed research and the latest innovations in technology, Nirman has developed concrete for a wider range of projects. Nirman Chemicals produces top quality concrete for many of the leading contractors and major players in construction.
These admixtures for concrete improve upon several main components and factors of the concrete. The enhanced concrete produced by Nirman is longer-lasting, stronger more damage repellent and has higher durability overall.
Nirman Chemicals limited offering a wide range of Chemical Admixtures for the different grades and types of concrete for Building segment and ensuring a ·complete Construction Care· to our Customer by proposing our NIROCRETE Range of products and also by optimising the mix design with variable cement and aggregate qualities to achieve high-qual ty concrete with extended durability at lower cost.
These products are retarding type high range water reducing admixture based on Polycarboxylic ether (PCE) molecules which adsorb onto the cement particles and disperses them through ionic charges cause electrostatic repulsion and steric hindrance The resultant dispersion reduces water requirement of the m x and increases workability of the concrete

Features:

• Ensuring a constant high-quality concrete at low water/ cement ratio
• Providing a concrete with extended workability at high temperature, without delayed strength
• Guaranteeing a concrete that meets the original specification from the fresh to the hardened stage.
• Offering a single, versatile admixture for many types of applications and
• Good dispersion even in mixes with high fines
• lower pumping pressure
• Resistance to segregation even at high workability
• Suitable for high volume replacement of GGBFS or fly ash in concrete mix
• Higher ultimate strengths
• Reduced shrinkage
• Increased ease in finishing concrete
• Increased durability

NIROCRETE Range comply with BS:5075 and ASTM-C-494 Type ‘A, D, F & G’ depending on dosage.

We are also offering the following others Chemical Admixtures which will fulfil the requirement of different type of concrete in Building segment.

• NIROCRETE ULTIMA range Are the superplasticisers based on new generation polycarboxylicether polymers, developed using special polymer-technology. which is the ultimate solution to produce economical, Self-compacting concrete, High flow concrete and Highgrade concrete with Very long workability retention and High workability without segregation and bleeding properties, it also enhance strength development process of
• NIROGOURO BCI: Is an organic Bipolar concrete penetrating corrosion inhibiting admixture containing molecules in which electron density distribution causes the inhibitor to be attracted to both anodic and cathodic Due to the good quality of its vapour pressure and distribution with the moisture within the concrete, these molecules migrate to the steel and form a monomolecular layer along the reinforcement in concrete. Thus corrosion vis-ii-vis micro cell formation is inhibited
• NIROPROOF IW: Is an integral waterproofing liquid admixture which added to the concrete/ mortar at the time of batching/mixing to resist the penetration of water through the capillary action or through water under pressure in hardened state of concrete and mortar.
• NIROPROOF CRY: An integral capillary waterproofing It contains specialist additives that plays role of catalyst in the formation of water-insoluble crystalline microstructures deep within the capillaries and interstices of cementitious matrix of concrete and mortars.
• NIROSET SR: Is a liquid retarder used for achieving an exposed aggregate finish on concrete by retarding the setting of cement paste in the surface matrix of concrete and then removing
• NIROSET NCA: Is ready to use Non-Chlorideliquid accelerating admixture for use in concrete, mortar and portland cement which reduces the setting times in general and specially under cold weather, leading to early high and ultimate increased In addition, it reduces bleed and segregation while improves workability. It does not contain any added chloride ions ensuring that the product does not contribute to the corrosion of reinforcing steel. Rather it helps in reduction of chloride attack on concrete.
• NIROFOAM : Is a foaming agent based on concentrated solution of selected surfactant materials which is diluted with water before use to produce light-weight pumped of poured concrete used in structures characterized by very high noise and thermic isolation and for low strength concrete filling.
