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

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 teachers role in the class room is to cater for these needs. Montessori believed that only a certain type of person suited the role of a Montessori teacher “The teacher must derive not only the capacity‚ but the desire‚ to observe natural phenomena. In our system‚ she must become a passive‚ much more than an active‚ influence‚ and her passivity shall be

The Montessori Method: A Rhetorical Analysis Maria Montessori graduated in 1894 from the University of Rome’s medical school‚ becoming Italy’s first female doctor. This was a feat that reinforced Montessori’s commitment to women’s rights. Living in the 20th century‚ Montessori noticed society’s use of science as an approach to improving education. She believed these strategies were scientifically irrelevant to the teaching of students. In her writing “The Montessori Method”‚ Maria Montessori
