Research paper for making hollow blocks

The evolution of the mass density as a function of compaction stress is given in Fig. The vibrocompaction decreases the inhibitory effect of the wood on hydration reaction of the cementitious composite and leads to an improvement of the mechanical performance limits.

The table below shows the ratio of the samples. Weight 3. The amount of cement replaced by mineral admixture in the concrete affected the compressive strength and the slump. Based on requirement of highway base material, strength performance test and feasibility analysis is conducted in this paper.

Based on recent studies, alternative building materials are cost effective, light weight when dry, and efficient to use. Type cement has been used for this research. Cement Cement is one of the binding materials in this project. We can observe that the rate of increase of compressive strengths can be slowed according to the sawdust substitution ratio.

A decrease of the maximum heat flux of different PSC concrete mixes and a slowdown of hydration reaction kinetics were observed. As the device quickly reaches the desired compaction stress, this decrease can be explained for PSC0, PSC30 and PSC60 by the speed of the introduction of the high load that blocks the granular arrangement of concrete under vibration.

For the water absorption test The method of concrete manufacture by vibrocompaction increases its mechanical strength.
