Characterization of various cement grinding aids and their impact on grindability and cement performance

Improvements in the sustainability and durability of building materials depend on understanding interfacial properties of various mineral phases at the nanometer scale. Tricalcium silicate (C3S) is the major constituent of cement clinker and we present and validate a force field for atomistic simulations that provides excellent agreement with available experimental data, including X-ray structures, cleavage energies, elastic moduli, and IR spectra. Using this model and available measurements, we quantify key surface and interface properties of the dry and superficially hydrated mineral. An extensive set of possible cleavage planes shows cleavage energies in a range of 1300 to 1600 mJ/m2 that are consistent with the observation of faceted crystallites with an aspect ratio near one. Using pure and hydroxylated surface models that represent the first step in the hydration reaction, we examined the adsorption mechanism of several organic amines and alcohols at different temperatures. Strong attraction between...

The effect of grinding aids on the fine grinding of limestone, quartz and Portland cement clinker

Engineered cementitious composite (ECC) is an exclusive type of cement mixture composite which imparts high ductility and high tensile strength. Over the decades, enormous strides have been made in creating ECC with extreme tensile ductility, on the order of several hundred times than that of normal concrete or fiber reinforced concrete. The experimental behaviour of ECC which is combined with polyvinyl alcohol (PVA) and steel fibers has been investigated in this research. The main aim of the research is to study the durability of ECC through compressive strength for long-term exposure condition under chloride, sulfate and combined sulfate–chloride environmental conditions experimentally. In the present work, six different ECC mixtures with constant water-cement ratio were prepared with the total volume fiber fraction (Vf) of 2%. ECC mechanical properties such as compressive strength, flexure strength and uni-axial tensile strength have been experimentally determined. The test results emphasize that the flexural strength and uni-tensile strength of the ECC specimens with the combination of 1.5% PVA and 0.5% steel fibers were improved as supposed to conventional ECCs. The durability property has been carried out only for the optimized dosage of fibers after exposed to aggressive solutions. The performance of optimized dosage of ECC mixture with hybrid fibers was barely affected by the aggressive solutions of chloride and sulfate–chloride when compared the same with water.
