This article presents the results of research on different properties of Ultrafine Marble Particles (UMP), Ultrafine Brick Particles (UBP) and of cement clinker. UMP and UBP are mixed at three different ratios (79:21, 77:23 and 81:19) to form alternative raw meal. These samples are burned at 1450°C for 30 min to produce cement clinker.

The standard thickness of white cement paste decreased from 30.5 % of the raw material to 26.0 % of the ultrafine white cement (d50=4.42 µm, d90=10.26 µm). The use of 2% naphthalene-based water reducer can reduce 15.4 % water consumption. The 3d compressive strength of pure ultrafine white cement sample reached 174 % of that of raw white cement.

In low cement, ultra-low cement, and cement-free castables, the dispersants used are mainly sodium silicate (water glass), sodium phosphate (sodium hexametaphosphate, sodium tripolyphosphate, etc.). The function of the dispersant is to increase the potential of the colloid in the castable and realize the dispersion of the ultrafine powder.

This improves the "packing density" of cement paste. It results in increased compactness and hence refined pore structure. As the porosity gets reduced, durability of the concrete structure improves. It has been observed that along with fineness one more parameter has major impact on the overall rheology and strength of the concrete.
