High Range Water Reducer - Sika
Sika ViscoCrete-2100. HIGH RANGE WATER REDUCING ADMIXTURE. Sika ViscoCrete-2100 can be dosed in small amounts to obtain water reduction from 10-15%, and will achieve water reduction up to 45% at high dosage rates. Sika ViscoCrete-2100 is suitable for all levels of water reduction.
Chemical Admixtures - Cement
Accelerating admixtures are especially useful for modifying the properties of concrete in cold weather. Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.

- What are superplasticizer admixtures?
- The superplasticizer admixtures evaluated are of recent commercial development by the cement industry and comprise admixtures based on melamine (Me), vinyl copolymer (VC), and polycarboxylates (PCE1, PCE2, and PCE3). The three polycarboxylates differ in their structural parameters.
- Which superplasticizer is best for precast concrete?
- PANTARHIT® F (FM) is a superplasticizer with accelerating properties suitable for producing ready-mix and precast concrete. PANTARHIT® FT100 (FM) is a high performance superplasticizer for producing high consistency concrete at low water/cement ratios in precast concrete plants.
- Are superplasticizer admixtures suitable for OPC?
- Superplasticizer admixtures are designed for OPC so, in presence of supplementary cementitious materials, such as metallurgical slags and combustion ashes, or in alkaline environments, their performance may differ.
- What is the difference between Polycarboxylate ether and superplasticizer admixture?
- As a consequence, the proportion of water necessary in the formulation is reduced . On the other hand, one of the most common superplasticizer admixture families currently used is polycarboxylate ether with branched side chains.
- What are plasticizing cementitious admixtures?
- 3.1. Chemical stability of admixtures in AAC: FTIR analysis Plasticizing cementitious admixtures are designed to improve the properties of Portland cement, which is hydrated with water that has a neutral pH. On the contrary, in AAC, solutions with higher pH are needed to hydrate/activate the cement.
- Why do admixtures lose their plasticizing properties?
- On the contrary, in AAC, solutions with higher pH are needed to hydrate/activate the cement. These can generate structural changes in the admixtures and, as a consequence, they can lose their plasticizing properties.
