Acute shortage and high price for river sand has lead to the adulteration of sand with salty sea sand which has raised serious concern among builders. The natural river sand was the cheapest resources of sand. However the excessive mining of rive bed to meet the increasing demand for sand in construction industry has lead to the ecological imbalance.
High Strength
The superior shape, proper gradation of fines, smooth surface texture and consistency in production parameter of chemically stable sands provide greater durability and higher stren ....etc

Abstract
This paper focuses on the experimental investigation carried out on high strength concrete reinforced with hybrid fibres (combination
of hooked steel and a non-metallic fibre) up to a volume fraction of 0.5%. The mechanical properties, namely, compressive strength, split
tensile strength, flexural strength and flexural toughness were studied for concrete prepared using different hybrid fibre combinations
steel polypropylene, steel polyester and steel glass. The flexural properties were studied using four point bending t ....etc

ENGINEERING PROPERTIES OF STRUCTURAL
LIGHTWEIGHT CONCRETE



INTRODUCTION

Structural lightweight aggregate concrete is an important and versatile material in modern
construction. It has many and varied applications including multistory building frames and
floors, bridges, offshore oil platforms, and prestressed or precast elements of all types. Many
architects, engineers, and contractors recognize the inherent economies and advantages
offered by this material, as evidenced by the many impressive lightwei ....etc

Concrete is a composite material composed mainly of aggregates (fines and coarse), cement and water. Cement and aggregates remain the main constituents, while aggregates alone constitute an important part of the volume of concrete. According to Alexander and Sydney (2005), between 70 and 80 percent of the total volume of concrete is occupied by the aggregate. With this large proportion of aggregate-occupied concrete, the aggregate is expected to have a profound influence on concrete properties, cost of production and ....etc
