Different types of natural coarse aggregate are available in the local market Bangladesh, which primarily imported from several regions neighboring country, India. This paper aims to find best locally for concrete preparation terms mechanical strength. It also reports on results an experiment investigation that looked at effects six different aggregate, namely Burimari, Bhurungamari, Bholaganj,...

High-strength concrete is one of the various special concretes that have become increasingly popular in recent decades. offers a higher strength-to-volume ratio than normal-strength concrete. However, design provision not explicitly served most building codes. This study focuses on shear strength high-strength and many factors influence strength, i.e., longitudinal reinforcement ratio. The was ...

Numerous research studies have been conducted to improve the weak properties of recycled aggregate as a construction material over last few decades. In two-stage concrete (TSC), coarse aggregates are placed in formwork, and then grout is injected with high pressure fill up voids between aggregates. this experimental research, TSC was made 100% (RCA). Ten percent twenty bagasse ash used fraction...

Hot Mix Asphalt (HMA) is the most commonly used in Malaysia for highways, interstates and roads due to its flexibility, economical, strong provide safe riding quality road users. Over years, increase of damage on pavement has become a severe issue although did not achieve design life. Hence, reduce defect, an improvised structures needed. Various studies have been conducted identify new materia...

The microbial community structure in various microaggregates in a loamy sand soil was investigated. The microaggregates were separated into outer and inner aggregates using a series of soil washes. Further physical fractionation of inner aggregates was achieved by separation into coarse and fine sand as macroaggregate fractions, coarse and fine silt as microaggregate fractions, and clay. Resear...

The flexural behaviour of concrete containing Foamed glass as partial replacement of coarse aggregate is investigated. The coarse aggregate was replaced with 0%, 25%, 50%, 75% and 100% Foamed glass. All other constituents were maintained the same. Reinforced concrete beams were cast using 2 bars of 8mm in diameter in the tensile zone. The density and compressive strength of concrete decreased a...
