Abstract
The influence of grinding aids (pure triethanolamine and ethylene glycol) on the properties of cements, their compatibility with an acrylate-based superplasticizer and the rheological parameters of mortars were investigated. The presence of surfactants influences the standard properties of cements and the effectiveness of the superplasticizer. The results of the heat of hydration and setting time measurements indicate a delay in the hydration process and an increase in the induction period duration of the surfactant-doped pastes, in relation to the reference sample without grinding aids. Triethanolamine increases early-age compressive strength; the effect was observed for both standard and superplasticizer-containing mortars. The presence of grinding aids decreases the slump flow of mortars and increases rheological parameters such as yield stress (τ0) and viscosity (η).
Highlights
Grinding aids, first introduced into cement manufacturing in 1930 [1], are surfaceactive substances that facilitate particle comminution during the milling process
In the production of Portland cement, grinding aids are added in small amounts in the range of 0.01 to 0.10% by weight of cement, according to the PN-EN 197-1 standard [1]
The results showed a delay in hydration and an increase in the compressive strength [10]
Summary
First introduced into cement manufacturing in 1930 [1], are surfaceactive substances that facilitate particle comminution during the milling process. The Effect of Various Grinding Aids on the Properties of Cement and Its Compatibility with Acrylate-Based Superplasticizer. The application of surfactants as grinding aids changes certain cement properties, such as water demand, setting times and compressive strength [1,2,6,7].
