Health is determined by several factors including genetic inheritance, personal behaviors, access to quality health care, and the general external environment (such as the quality of air, water, and housing conditions). In addition, a growing body of research has documented associations between social and cultural factors and health (Berkman and Kawachi, 2000; Marmot and Wilkinson, 2006)

CIVL 1101 - Part 6 - Concrete Agregates. Part 6. Concrete Aggregates. Aggregates generally occupy 70 to 80% of the volume of concrete and therefore have a significant effect on its properties. Strength of concrete and mix design are independent of the composition of aggregate, but durability may be affected. Aggregates are classified based on

There are many tests which are conducted to check the quality of aggregates. Aggregates are very important component of concrete, so the quality really matters when it comes to aggregates. Various test which are done on aggregates are listed below. 1. Sieve Analysis 2. Water Absorption 3. Aggregate Impact Value 4. Aggregate Abrasion Value 5. […]

Nov 05, 2018 Cement is one of the key stabilizers for earth constructions since Roman civilization. The invention of cement was one step in the human civilization. However, cement has many issues especially when it comes to the environmental conservation. The production of cement creates a lot of carbon dioxide and destroys the natural setting to some extent due to the high consumption of clay and lime
