RANSCONMIX-SP410 is a High Range Water Reducing Admixture for High performance, High strength and durable concrete. It is based on a Polycarboxylate Ether (PCE) Polymer. The main polymer backbone has carboxyl groups for the adsorption on the surface of cement particles and alkoxy polyether lateral chains that keep the particles physically away from each other. This phenomenon of separating discrete solid agglomerating particles is known as Steric Hindrance. This result in superior fluidity of the mixture combined with better retention of workability (slump) as compared to the conventional super plasticizers based on Naphthalene or Melamine formaldehyde polycondensates. RANSCONMIX-SP410 comprises of particles less than 1/50 the size of cement grains, and is synthesized through ionic.Polymerization in nano-scale.

RANSCONMIX-SP410 is a High Range Superplasticizer (water reduction up to 40% in control concrete) with superior cement dispersion ability to provide extremely high slump values, even to concrete mixtures with water-to-cement ratio of less than 0.30.

RANSCONMIX-SP410 can provide slump retention of more than 120 minutes after mixing at higher than ambient temperatures (35??C or more).

Properties:

• RANSCONMIX-SP410 is highly dosage efficient – a much smaller dosage as compared to conventional superplasticizer is only sufficient.
• RANSCONMIX-SP410 imparts high flow ability to the mixture so as to fill the formwork under its own weight (self-compacting ability) without any voids or segregation of aggregates. This self-compacting concrete (SCC) maintains fluidity for longer periods unlike conventional Superplasticizer that suffer rapid slump loss.
• RANSCONMIX-SP410 can be used as a pumpability enhancer combined with plasticizing effect which allows high range water reduction leading to phenomenal increase in compressive strength, impermeability and durability.
• RANSCONMIX-SP410 has no effect on the setting time of concretes and develops high early strength that allows rapid progress in large scale civil engineering applications.
• RANSCONMIX-SP410 is ideal for pre-cast and prestressed concrete products. The very high fluidity of the concrete mixtures facilitated by RANSCONMIX-SP410 results in smooth surfaces on removal of formwork.

Dosage : (0.4% to 1.2% [v/w])

As with most commodity concrete additives, the efficiency obtained by the use of RANSCONMIX-SP410 is dependent on dosage, water to-cement ratio, the nature of constituent materials such as cement, fly ash and ground granulated blast furnace slag. The type of cement, its fineness and the C A (tricalcium aluminate) content are important parameters that influence the performance of the chemical admixture.

It is therefore necessary to assess the performance of concrete in its conditions of placing to arrive at optimum dosage of RANSCONMIX-SP410 to ensure desirable plastic and hardened concrete properties.

Compatibility With Cement:
RANSCONMIX-SP410 can be used with all types of OPC, composite cement (PSC and PPC), Silica Fume, Metakaolin, and Rice Husk Ash (RHA), Pulverized Fuel Ash (PFA) and Ground Granulated Blast Furnace Slag (GGBFS).

Effects of Over Dosage:
An over dose of double the recommended amount of RANSCONMIX-SP410 will result in very high workability and some retardation of setting time will occur. However, the ultimate compressive strength will not be impaired.

Mix Design:
RANS has a dedicated advisory service on concrete mix Design and can be controlled if assistance is required

Storage:
