Introduction Concrete mixtures can be designed to provide a wide range of mechanical and durability properties to meet the design requirements of a structure. The compressive strength of concrete is the most common performances measure used by engineer in designing buildings and other structures. The compressive strength is measured by breaking concrete specimen in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting

The poem ’Concrete Angel’ by Martina Mcbride is a very strong and outspoken poem. This poem represents some of the large issues we deal with in our society today. The poem touches base with the children that struggle with abuse from their parents or other family members. Martina uses many symbolistic words that represent child abuse.

1. INTRODUCTION Concrete is a widely used building material‚ many concrete pavements such as bridge deck‚ highway pavements and airfield runways are constructed all over the world‚ due to its superior properties such as high strength‚ good stability‚ abrasion resistance and anti-slippage. However‚ concrete is a poor electrical conductor‚ especially under dry conditions. Concrete that is excellent in both mechanical and electrical conductivity properties may have important applications in the electrical
