Effect of amine and glycol-based grinding aids utilization rate on grinding efficiency and rheological properties of cementitious systems

Evaluation of fresh state, rheological properties, and compressive strength performance of cementitious system with grinding aids

“…Researchers were emphasized that the dispersion effect of GA adsorbed on the particle surface is related to the surface properties of the particles such as changing surface energy, zeta potential, and aggregation energy. 37,40 In the context of this…”

“…GA3, containing 100% TIPA, was identified as the most effective GA, corroborating findings from other researchers. [40][41][42] Additionally, Mishra et al 39 asserted that the utilization of TIPA as a GA results in a more significant reduction in the adsorption energy of cement particles compared with TEA. The application of TEAand TIPA-based GAs led to a decrease in the surface energy of C 3 S from 450 to 97 and 68 mJ/m 2 , respectively.…”

“…Similar findings have been documented in previous research studies. 40,42,45 Since the PSD of cement with the same Blaine fineness value may differ, Blaine fineness is not sufficient as a precise fineness criterion. 46 For this reason, the effect of GA on cement PSD was investigated.…”

“…The adverse effect of using cement with a narrower PSD on admixture performance has been noted by other researchers as well. 18,40 In instances where PCE is incompatible with the cement or other additives employed, issues such as a sudden loss of consistency or an increase in viscosity may arise in the mixture. 3 When PCE is introduced into mixtures containing GA, there is a potential for GA to adsorb onto the cement particles, reducing the adsorption affinity of PCE.…”

Determination of Setting Times of Mortar Mixtures Prepared with Cement Having Different C3A Ratios

“…The fresh-properties of cementitious systems depend on many physical and chemical parameters. The rate of hydration and workability of the cementitious system are significantly affected by some factors such as the chemical composition of cement, especially its C 3 A content and fineness as well as the gypsum type and amount added to its clinker during the manufacturing process (Zingg et al, 2009;Karakuzu et al, 2021;Kobya et al, 2022). C 3 A is the most reactive component of cement (Mehta & Monteiro, 2006;Karakuzu et al, 2022).…”
