Differences between mortar vs concrete There are many who are confused on the differences between cement, mortar and concrete. Previously, we discussed thedissimilarities of cement and concrete. Now let’s discuss about thedifferences between mortar and concrete. ...
PROBLEM TO BE SOLVED: To provide a cement admixture, a cement composition and mortar or concrete using the same, which are used in construction industry and excellent in rapid hardening and suppressing neutralization. SOLUTION: The cement admixture contains a hardening accelerator and a slowly cooled...
The measurement of the mechanical characteristics (fracture energy, tensile strength, elastic modulus and thermal damage parameter) of five cementitious materials, cement paste, mortar, ordinary concrete and two HPC concretes were performed by three-point bending tests after heating/cooling cycles at 120...

This article reports the acoustic emission (AE) study of precursory micro-cracking activity and fracture behaviour of quasi-brittle materials such as concrete and cement mortar. In the present study, notched three-point bend specimens (TPB) were tested under crack mouth opening displacement (CMOD)...
