Nowadays under the conditions of intensively developing construction production, hardening time and strength Portland cement are becoming more relevant research issues this type binder. The basic requirements to stated in normative industry documents considered. limits normal fast-hardening given. Raw materials for production high-strength must be homogeneous provide a high degree fineness bind...

Although primarily deemed to be an ornamental stone, granite may also ground into fines for use in cement mortars, where it exhibits high strength and durability. Both the 40K present stone natural decay series of its uranium, thorium actinium components exhibit activity concentrations. An understanding is therefore needed correlation among different particle sizes aggregate assess their contri...

Due to the clinkerization process during Portland cement production, large amounts of CO2 are emitted, increasing effects related climate change (approximately 5-10% global emissions come from production), consequently, seek for alternatives mitigate these high necessary. The use supplementary cementitious materials (SCM) partial replace Portand clinker/cement has been subject different researc...

Ceramics based on rhenanite CaNaPO4 with density of 0.94 g/cm3 and compressive strength 10.3 MPa was obtained via firing at 900 °C composite cement-salt stone prepared from a hardening powder mixture calcium citrate tetrahydrate Ca3(C6H5O7)2∙4H2O sodium dihydrogen phosphate NaH2PO4. The phase composition the samples cement–salt represented by monetite CaHPO4, unreacted tetrahydrate. According t...
