Abul Kalam Azad‚ and Mohammed Abdul Hameed A STUDY OF SELF-COMPACTING CONCRETE MADE WITH MARGINAL AGGREGATES Shamsad Ahmad∗‚ Abul Kalam Azad‚ and Mohammed Abdul Hameed Department of Civil Engineering King Fahd University of Petroleum & Minerals Dhahran‚ Saudi Arabia 1. INTRODUCTION Self-compacting concrete (SCC)‚ developed first in Japan in the late 1980s‚ represents one of the most significant advances in concrete technology in the last two decades. SCC was developed to ensure adequate compaction

different skin sites are studied and an experimental study of dispersal of MRSE during exercise in a test chamber and during operations‚ using two different types of scrub suits are made. Nasal carriage was found among 28.4% samples from women and 33.3% from men. Among five skin-sampling sites‚ carriage of MRSE was most frequent on the cheek (50%) and in the axilla (24%) and least frequent in the perineum (5%). On the other hand‚ the dispersal of MRSE is considerably more associated with carriage

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

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

A Short History of Dr. Maria Montessori and her Methods Teaching a two years old child how to be independent‚ responsible and confident sounds impossible‚ but more than 100 years back an Italian doctor named Maria Montessori made it possible. As she believed "the study of child psychology in the first years of life opens to our eyes such wonders that no one seeing them with understanding can fail to be deeply stirred. Our work as adults does not consist in teaching‚ but in helping the infant mind

Nature of Abstract Art Meyer Schapiro (1937) Before there was an art of abstract painting‚ it was already widely believed that the value of a picture was a matter of colors and shapes alone. Music and architecture were constantly held up to painters as examples of a pure art which did not have to imitate objects but derived its effects from elements peculiar to itself. But such ideas could not be readily accepted‚ since no one had yet seen a painting made up of colors and shapes‚ representing

Ronnie Green Informative Abstract June 28‚ 2011 Image gap is the difference between how a person wants to look and sound compared to how they are actually viewed by others. Projecting your desired image can build trust and is critical to successful communication. Projecting an inappropriate image‚ however‚ can erode trust and cause others to doubt your abilities. Four components of your overall image are your projected first impression‚ your depth of knowledge‚ your breadth of knowledge‚ and
