EXPERIMENTAL STUDY ON FRESH AND MECHANICAL PROPERTIES OF CONCRETE REPLACED WITH MINERAL ADMIXTURES

Concrete is a group of cement, fine and coarse aggregate and water. The present study is about the replacement of cement with metakaolin and quarry dust. Because, now a days the waste products are increasing every day. To reduce those waste products and to improve the strength and durability of concrete, the cement is replacing with quarry dust and metakaolin. Here, the cement firstly replaced with 25% of quarry dust and this as constant replacement of cement without loss of standard strength of cement. After the replacement of 25% of quarry dust, the mixture is replaced with 0%, 2.5%, 7.5% , 10% and 12.5% metakaolin. By taking the above replacements in cement, the concrete mixture is to be prepared to find the strength properties like compressive strength, splittensile strength and flexural strength of concrete. The strengths of the concrete were found at the age of 7days, 28days and 90days.
