Cement Additives Sika
Cement additives are materials added to cement for the optimization of the cement properties and the cement grinding process. Sika has developed a polycarboxylate polymer-powered grinding aid technology, which is The ordinary Portland cement (OPC)-based solidification process is used extensively to reinforce soils due to its available and good bonding properties. Alternative products are used in cementitious materials to enhance the strength and to reduce OPC consumption. In this study, the effect of additive type and mass fraction on the Influence of Some Additives on the Properties of OPC Solidified

The Effect of Various Grinding Aids on the Properties of Cement
The grain size distribution of cements with grinding aids is narrowed, compared with the reference cement without additives, which means that size of their grains is more homogeneous (Figure 2). Slight differences can be noticed in the range of 10 ÷ 40 µm, where CEM ‘0’ has about 30% fewer grains, compared with CEM + TEA and Our knowledge of strength and performance enhancer can be applied for cements from ball mills as well as from VRM’s. Cement particles with a diameter below 3 µm are known to have no or very little influence on the strength development. On the other hand, the graph above shows that SikaGrind® VRM-40 shifted a considerable share of the cementCEMENT SikaGrind® FOR VERTICAL ROLLER MILLS

Cement Additives Concrete Solutions Sika South Africa
Cement additives are materials added to cement for the optimization of the cement properties and the cement grinding process. Sika has developed a polycarboxylate polymer-powered grinding aid technology, which is able to improve the performance of traditional grinding aids. A typical example is SikaGrind®-840. Strength Enhancer.This invention relates to a method of producing enhanced strength portland cements. Under the process of this invention, certain portland cements, in particular those containing at least 4% C 4 AF and up to 0.2% of a strength enhancing additive comprising triisopropanolamine, exhibit a marked increase in 7 and 28 day compressive strength.

A renewable admixture to enhance the performance of cement
Aiming to reduce the carbon emission associated with ordinary Portland cement (OPC) based cementitious materials, this study explores a ubiquitous biomolecule, Tannic Acid (TA) to enhance the eco-efficiency of cement mortars through a pre-hydration process. To this end, a small amount of cement is first hydrated in the presence of TA. The OPC content can be <50 wt% in LC3 and LC3+ cement with C-S-H seeding to achieve comparable strength.
