This study aims to compare the developments of mechanical properties and autogenous shrinkage related alkali-activated materials-based concrete (AC) ordinary Portland cement-based (OC) against curing age degree reaction. Temperature Stress Testing Machines are utilized monitor evolution internal tensile stress cracking occurrence in restrained concrete. It is found that AC shows lower strength-...

The article proposes a method for determining temperature fields and stresses during the construction of massive monolithic structures in two-dimensional axisymmetric formulation. solution is performed using finite element method. calculation takes into account shrinkage concrete, as well change its physical mechanical characteristics over time. problem calculating foundation wind turbine prese...

In this paper, different types and particle sizes of nanoclay (nano-metakaolin—NMK—and nano-attapulgite—NMA—clay) were selected to study the effect on properties cement-based cementitious materials. The stability dispersions was analyzed. effects mechanical cracking behavior cement mortar discussed. crack propagation analyzed by flat knife-edge induced constraint ring experiments. research show...
