Buildrock provides a wide range of concrete admixtures with innovative options for concrete mix design, whether it's for substantially reducing the water content of a mix (e.g. with Buildrock® AX 3101 ),using a more economical mix design or achieving sufficient early strength. Buildrock® concrete admixtures help you meet the challenges of modern concrete technology and the construction business.
It fulfils the need for concrete with long workability retention of 4 hours plus. This product exhibits high water reducing capability for a given concrete mix design and requires only dosage optimization at site.
It is a low viscosity high performance polycarboxylic technology based chemical admixture which can consolidate under its own weight. Suitable for placing in difficult conditions and in sections with congested reinforcement because of its filling ability, passing ability and segregation resistance.
It is a method of applying concrete that is generally self supporting without the need for form work and is often referred to as Gunite (dry mix) or Shotcrete (wet mix).
It is used for road-laying and requires compaction of a very specific concrete design at a consistency level that allows the form to move continuously. The grade of PQC will be decided by various traffic studies, need for trouble-free service life and the modulus of subgrade reaction, etc.
It is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. These can be used as water-reducing and retarding admixture which is beneficial for extending workability of RCC.Also to produce air entrained concrete for increased durability and resistance to entrained by frost and decaying salts.
It is poured into a wooden or steel mold with wire mesh or rebar. This mold may also have prestressed cable, if needed. There are low-viscosity, single component PCE based admixtures for low slump, normal slump and for flow concrete with slump retention which are ideal for precast segments, for large volume of concreting in precast industries and for concrete poured in structures having congested reinforcement.
Concrete becomes saturated when a water body comes in contact with it and water flows slowly under pressure due to interconnecting capillaries. The Integral system works with the matrix of concrete or mortar, giving the concrete itself a waterproof quality.
