Most concrete produced today includes either chemical additions to the cement, chemical
admixtures in the concrete, or both. These chemicals alter a number of properties of …

Efforts to model and simulate the highly complex cement hydration process over the past
40years are reviewed, covering different modeling approaches such as single particle …

The fundamental chemical hydration process of portland cement and its main mineral
component, tricalcium silicate, was studied by investigating the effects of various additives. A …

The objective of this study is to link the molecular structure of polycarboxylate-ether-type
superplasticizers with the performance of cementitious systems in order to develop new …

Polycarboxylate ether surperplasticizer (PCE) has been commonly used and studied to
enhance flowability of cementitious materials. However, the effect of PCE addition on …

As the most effective superplasticizer, the comb-like PCE polymers also severely retard early
cement hydration and hence decelerate early strength growth of concrete, which is …

Concretes intended for printing need specific rheological properties that are not found in
traditional ones. Printable concretes must have as much consistency as possible and, at the …

A series of organosilane-modified polycarboxylate (PCE) superplasticizer were synthesized,
in which acrylic acid (AA) was partially or completely substituted by 3-(trimethoxysilyl) propyl …

AC impedance spectroscopy (ACIS) is a promising technique for monitoring the
microstructure evolution of fresh cement paste in real-time. This paper compared the change …

Fluidity control and setting adjustment are two critical issues for practical applications of
calcium sulfoaluminate cement because of rapid hydration. A commonly used comb-like …
