Determination of compressive strength of cement ...

2021-6-11  Theory: Among physical properties of cement, compressive strength is the most important property. When cement is used for important structures, compressive strength test is always carried out to ascertain quality of cement. Strength test is not made on plain cement due to excess shrinkage and cracking of plain cement

Compressive strength of cement -(Procedure and formula

2021-8-26  Compressive strength of the cement is the property of cement which specifies how much load it can withstand when cement is made into a hardened mass mixing with standard sand and water. The process of testing compressive strength of concrete and and cement may be somewhat same but the materials required for preparing cubes are different.

2017-8-25  Zhou and Jia (2010) developed a low-density and high-compressive strength cement slurry based on the theory ofparticle grading over numerous experimentations. The per-formance of the compressive strength of the cement slurrydeveloped has been improved over the existing one. Ordi-narily, class G cement is one of the types used for sealing offof formations because of its ability to withstand high resis-tance of pressure, temperature, and sulphate. Despite thesequalities, additives are required to improve the properties ofthe cement (Xi et al. 2010). Bayu et al. (2010) concluded intheir work that the addition of 0.2 % of lignosulfonate to acement slurry increased compressive strength. Above thisvalue, compressive strength was noticed to have reduced.Performance of other additives to enhance cement operationsto optimally increase compressive strength during cementoperation depends on the correct proportion of each of theadditives. The best way is to subject these additives to aseries of experimental runs, which is usually time consum-strength of oil well class G cement
