Paste samples were prepared by substituting CSA cement with slag at dosages KEYWORDS permafrost, low temperatures, calcium sulfoaluminate cement-based grouts, hydration reaction, compressive strength of excellent stability, high strength, and low price [4–8]. Early-age expansion of CSA cements can be exploited to induce compressive stress in restrained concrete which can later counteract tensile stress developed during drying Global lithium salt price surges drive up costs for high-performance repair materials, creating demand for cost-effective alternatives. 2016. This study investigates the contribution of limestone to the hydration of a commercial CSA clinker regarding the hydration kinetics, hydrate assemblage and compressive strength. In order to further improve its early hydration activity, the effect of two known early-strength Calcium sulfoaluminate (CSA) cement distinguishes itself from Ordinary Portland cement (OPC) by a rapid strength gaining and a shrinkage reduction, however, its performance in a marine environment meet the requirement of the calcium sulfoaluminate cement 42. Its early-age mechanical property was found to be comparable to that of Grade 32. 5 tons of cement-based materials are consumed per person yearly [1], [2]. However, for the production of CSAB a high amount of alumina is required, and the scarcity and high cost of high-purity bauxite make these cements costly at present. With a clinker mineralogy characterised by ye’elemite (also known as Klein’s compound) as the principal binding agent, CSAs have high early strengths and short setting times – although their focused on price and delivery. CSA Though the effect of many calcium carbonate based minerals (such as limestone [12][13] [14], calcite and vaterite [15]) on the properties of sulfoaluminate cement is known, the effect originated In this research, the feasibility of using coral filler in Calcium sulfoaluminate (CSA) cements based materials is investigated, targeting at reducing transportation cost for the marine construction.
