Abstract:
The main objective of this research is to produce structural light weight concrete using natural aggregate and optimization of strength properties. Actually aim is to Produce such a light weight which in addition to its light weight advantages poses construction possibilities as structural concrete in slabs, beams, and columns. Based on researches done in providence with a rich reservoirs of mineral aggregate mine with desired strength properties and this kind of aggregate was used in above mentioned concrete mixes. In current research various samples of this mine have been investigated as light weight aggregate in light weight structural concrete mixes. In addition to above not only it was important to produced concrete but also it was essentially necessary for researchers that produced mix designs to be practical in concrete practices and has economic benefits. Tests done on the aggregate in this research include followings: Identifying the aggregate from geological point of view measurement of water absorption in varieties of time-Density in air dried and saturated dry surface states(SSD)-defining aggregate water content from dried in air state to oven dried state and aggregate compressive strength. Tests done on concrete samples: Measurement of compressive strengthtensile strength-slump test.
