Aggregates for Concrete Aggregates are inert granular materials such as sand‚ gravel‚ or crushed stone that‚ along with water and cement‚ are an essential ingredient in concrete. Aggregates are the most mined materials in the world. For a good concrete mix‚ aggregates need to be clean‚ hard‚ strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates‚ which account for 60 to 75 percent of the total volume

Since 1980s‚ the coagulase-negative staphylococci (CoNS) ) is a primary consideration in the rise of surgical site infections. The Staphylococcus epidermidis is the predominant CoNS on human skin and methicillin-resistant are the isolates of CoNS that showed an increasing amount where perioperative prophylaxis are not effective‚ methicillin-resistant Staphylococcus epidermidis (MRSE) is then used in the study. The aim of the present investigation was to evaluate staff of the operating department

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 purpose of this experiment was to determine the effects of temperature on the elasticity of rubber bands. There were three hypotheses: If the 0.157 cm rubber bands are heated to about 100˚C in water for one minute‚ then the rubber bands will stretch to approximately 60 cm; If the 0.157 cm rubber bands are cooled to 0˚C in water for one minute‚ then the rubber bands will stretch to approximately 40 cm; If the 0.157 cm rubber bands are left in room temperature water for one minute
