Shear Strength of Concrete Beams made with Belitic Calcium Sulfoaluminate Cement
<p>The need for a cleaner alternative to portland cement (PC) concrete has led to increasing interest in alternatives to PC. Structural properties of most of these alternative cements are still an open research topic. One promising alternative cement is belitic calcium sulfoaluminate (BCSA) cement. …

Early-age hydration and volume change of calcium sulfoaluminate cement-based binders
… to allay shrinkage-induced stresses is to use calcium sulfoaluminate (CSA) cement whose early-age expansion in restrained condition induces compressive stress that can be utilized to counter the tensile stresses due to shrinkage. In addition to enhancing the resistance against shrinkage …

Influence of lightweight aggregate and calcium sulfoaluminate cement on deformation of ordinary Portland cement mortar and concrete
… lightweight aggregate (LWA) and usage of calcium sulfoaluminate (CSA) cement are two common methods applied in shrinkage mitigation. Pre-soaked LWA supplies additional moisture to cement paste during hydration, thereby compensating for the water consumption that occurs during hydration and …

Using BCSA Cement to Repair Waterway Transportation Structures
… time for maritime structures. BCSA (belitic calcium sulfoaluminate) cement is a promising material to perform this type of repair due to its properties. BCSA cement is a fast-setting hydraulic cement capable of reaching compressive strengths greater than 4000 psi (27.6 MPa) in less than 2 …

Improving the Sustainability of Performance-Based Concrete Overlay Mix Design made with Rounded Aggregate
… as river gravel, to improve workability, reduce cement usage, and enhance overall sustainability. The research is divided into three integrated phases. The first phase focuses on optimizing aggregate gradation using the modified void ratio method, combining the Power 45 and Tarantula curves to …

Circular dry cement inclusions: a novel approach to stabilising clay soil
… or not a deliberate inclusion of dry Portland cement would induce consolidation in a clay soil, by transferring and fixating pore water into the cement and changing the structure of the surrounding soil. Laboratory prepared kaolin clay was the soil material adopted for testing purposes, with …

Development of foamed concrete : enabling and supporting design
… factor in stability as evidenced by the use of Calcium Sulfoaluminate cement, CSA and CEM I 52.5R cement which increased the setting times. Stability was drastically achieved even at lower density 300 kg/m3. Blends of CSA with CEM I 52.5R and fine fly ash, FAf, demonstrated similar …

Modification of crumb rubber cement interface and its effect on strength and viscoelastic properties
… due to the incompatibilities between rubber and cement paste. The limitations related to the use of crumb rubber concrete are related to the interfacial transition zone between rubber and paste. Due to mismatches in free surface energy, coefficient of thermal expansion, and elastic modulus …
