TYPES OF BUILDING MATERIAL USED IN CONSTRUCTION Building material  is any material used for construction purpose such as materials for house building. Wood, cement, aggregates, metals, bricks, concrete, clay are the most common type of building material used in construction. The choice of these are based on their cost effectiveness for building projects. Here are some: 1. Concrete What it is:  a mix of cement, aggregate, and water. Uses : Traditionally used for supports, walls, floors, and exterior structures like driveways or patios, concrete is growing very popular in home construction for such diverse purposes as countertops and fencing. It is durable and resistant to climate, pests, and natural disasters. However, its manufacture results in a high rate of greenhouse gas emissions. Go green:  Look for concrete made with recycled content or energy-efficient, non-toxic autoclaved aerated concrete (AAC). 2.  Cement Second in the list is Cem

CIVIL ENGINEERING TIPS AND TRICKS -  A CIVIL ENGINEER MUST KEEP THESE IN MIND WHILE AT SITE. Points to be kept in mind while at any construction site.  Following are some general points which are to be kept in mind while having a day at construction site: 1. For dowels rod minimum of 12 mm diameter should be used. 2. 36 mm diameter is the maximum diameter bar used for lapping. 3. Maximum free fall of Concrete = 1.50 m 4.  Longitudinal reinforcement not less than 0.8% and more than 6% of gross C/S. 5. PH value of construction water should not be less than 6. 6. Water absorption of bricks should not be more than 15 % 7. Minimum thickness of slab = 125 mm 8. Maximum chair spacing = 1 m 9. Minimum no. of Bars in square column = 4 10. Minimum no. of Bars in round column = 6 11. Density of building materials:              1. Bricks = 1600 to 1920 kg/m3              2. Concrete Block = 1920 Kg/m3              3. RCC = 2310 to 2700 kg/m3 Hope you like the
