3.2. Chemical admixtures. Two superplasticizers (SP – naphthalene-based and melamine-based) were used at low W/C with cement A and microfine cement mixes (G, H, I, and J). The amount of SP used was between 1.0% and 1.2% by weight of cement.
Enables fluid cement grout mixtures to be formulated on the job site to accommodate specific site conditions. Compatible with various types of cement, including regular cement, high early strength cement, sulfate-resistant cement and microfine cement, as well as with other grouting admixtures.
Spinor A12 is a product range of fine to ultra-fine blast furnace slag binders with a maximum grain size distribution from 48 microns to 6 microns. Spinor A12 consists of grains finer than 12 microns and 12 is the coarser grain size. Spinor A12 is manufactured at a dedicated manufacturing facility under close quality control specifications which guarantees optimized and consistant quality and ...
To improve the durability of reinforced cement concrete structures, steps such as the reduction of water-cement ratio by compatible admixtures, reduction of calcium hydroxide generation in the concrete by using supplementary cementitious material, and increase in the packing density of the paste component by using compatible microfine materials ...
Cement is the main ingredient of cement-based grouts and its type should be determined according to the grain size distribution in the site-specific project. This means that in coarse soils, Portland cement may be considered efficient, but as the soil grains become fine, other types of cement such as ultrafine, microfine, and superfine cements ...

(Admixture for Pumped Concrete & Grout) TamCem 77TG is a special "consistency modifier" for concrete and grouts with no water reduction, air entrainment or retardation properties. It is a non-chloride liquid admixture designed to increase pumping efficiency, reduce segregation and enhance viscosity of high slump mixes.
In the second project, five aggregates with varied shape and texture were used to make concrete with microfines, chemical admixtures, and supplementary cementing materials. Significant variations due to the combined effect of shape and texture of aggregate, .
The use of a variety of additives and admixtures in microfine and regular cement-based grout formulations has become routine in advanced professional grouting practice. They play an important role in producing more durable grouts with improved rheological and set characteristics than could be obtained using only neat cement suspension grouts.
