Corrosion of reinforcements has been one of the major challenges that the civil engineers have been facing. Corrosion leads to the formation of rust which results in the spalling of concrete which in turn leads to the exposure of rebars to the aggressive environment. This will accelerate the ill effects and ultimately leads to the break down of the structure. Corrosion mainly occurs in areas of aggressive environment such as coastal regions. It is very important that corrosion of reinforcement must be prevented in order to have a durable struct ....etc

Abstract

Civil engineers are now-a-days being offered a variety of reinforcing steels to resist corrosion of steel in concrete. Two in particular, CRS and MMFX , will be discussed in this write-up However, the author stresses that reinforced concrete construction professionals need to refocus their attention on concrete, the material they know best, rather than on the metallurgical mysteries expounded by specialists from another discipline. After all, as every civil engineer worth his salt knows, concrete is the first line of defence in th ....etc

Introduction
The sun radiates energy onto Earth by means of light or heat. Humans have been harnessing this energy for centuries, and it is one of many types that are considered a renewable energy resource, that is, one that is naturally replenished. Photovoltaic s (PV) is the field in which new technologies and applica ....etc

ABSTRACT:
A new technique for reinforcing rubble stone masonry walls (double and triple-leaf walls), when it is required to keep the fair-face masonry. The reinforcement technique consists of a continuous mesh made of tiny steel cords embedded perfectly in the mortar joints after a first repointing, and anchored to the wall by means of galvanized steel eyebolts driven into the facing. A second repointing covers the cords and the heads of the eyebolts completely. T ....etc

use waste human hair fibre reinforcement concrete pdf

Fibre reinforced concrete can offer a convenient, practical and economical method for overcoming micro-cracks and similar type of deficiencies. Since concrete is weak in tension hence some measures must be adopted to overcome this deficiency. Human hair is strong in tension; hence it can be used as a fibre reinforcement material. Hair Fibre (HF) an alternate non-degradable matter is available in abundance and at a very cheap cost. It also creates environmental problem for its decompositions ....etc

Most brickwork is built without reinforcement. Historically, mortar was of low strength, and the bonding of the masonry units provided strength to the panel. Thick walls had to be bonded through the thickness as well as along the length of the wall, and old construction textbooks show in detail the ways of bonding headers with stretchers in alternate courses to avoid any continuous vertical joints.Bonds Nevertheless, the bending strength of a panel of brickwork is limited because the bricks themselves are much weaker in tension than in compress ....etc

ABSTRACT

The study investigates the characteristics strength performance and durability of Groundnut Shell Ash (GSA) blended cement concrete exposed to sulphate environments. The principal characteristic measured was the compressive strength of Ordinary Portland Cement (OPC) concrete and OPC/GSA concrete at varying substitution levels of 0%, 5%, 10% and 15% after curing in water and three chemical solutions (MgSO4 , NaSO4 and Ca2 SO4 ) of varying concentrations of 0.5%, 1.5% and 2.5% each at 56 day hydration period. The results showed that the ....etc
