Method of calculating the optimal sand content in normal-weight concrete
In the practice of proportioning concrete compositions, the optimum sand content in a mixture of aggregates is usually found empirically. The disadvantage of this approach is the considerable complexity and duration of the required tests.

Prediction of flexural fatigue life and failure probability of normal weight concrete
Fatigue life has to be considered in the design of many concrete structures at various stress levels and stress ratios. Many flexural fatigue test results of plain normal-weight concrete are available in the literature and almost every set of test ...

A model to estimate the durability performance of both normal and light-weight concrete [PDF]
There has been an increasing focus on the development of test methods to evaluate the durability performance of concrete. This paper contributes to this focus by presenting a study that evaluates the effect of water accessible porosity and oven-dry unit weight on the resistance of both normal and light-weight concrete to chloride-ion penetration. Based

Mechanical behaviour evaluation of scrab tire based rubberized lightweight and normal structural concrete and response at elevated temperatures [PDF]
In recent years, the exponential increase in the world population had led to sharp increase in discarded scrap tires, creating a serious ecological problem. In addition, environmental and social damage that occur during the extraction of aggregate is one

TORSIONAL AND CRACKING BEHAVIOURS OF NORMAL WEIGHT AND COCONUT SHELL LIGHTWEIGHT CONCRETES [PDF]
Modern-day structures using conventional concrete, which is tall and aesthetically pleasing is in need of torsional strengthening. The ability of a structure to withstand twisting forces about a longitudinal axis is called torsional strength.
