Effect of shrinkage reducing admixture on early expansion

This research examines the influence of presence of shrinkage reducing admixture (SRA) on expansion, hydration, and strength evolution of calcium sulfoaluminate-based expansive agent (CSA-based EX) blended with ordinary portland cement (OPC) in the absence of initial moist curing.

CSA BINDER - Tangshan Polar Bear Building Materials Co.,Ltd

The amount of CSA Binder needed to obtain a specific setting time varies considerably depending on the origin of the Portland cement and performance can be modified with the use of additives. The strength development of CSA Binder/Portland cement and/or Calcium Sulphates depend on the nature of the Portland cement and/or Calcium Sulphates used.

Development of self-stressing Engineered Cementitious

the mass ratio of CSA to OPC, both low shrinkage and expansion effects could be obtained [17,18]. Expansive cement enhances the volume stability of concrete and can even lead to the expansion of concrete [19]. By replacing OPC with CSA, the expansion increases first and sub-sequently decreases after reaching a peak [20,21].

On the interaction of Class C fly ash with Portland cement

Calcium sulfoaluminate (CSA) cements were developed with the goal of reducing shrinkage-induced cracking [].It is a well-known fact that the hydration of CSA cement results in formation of ettringite which can cause expansion [2,3,4,5].Ye’elimite (4CaO·3Al 2 O 3 ·SO 3) is one of the main phases present in CSA cements along with belite (2CaO·SiO 2), calcium sulfate (CaSO 4), and calcium
