Title

UTILIZATION OF DEMOLISHED CONCRETE AGGREGATE AS REPLACEMENT OF NATURAL AGGREGATE IN CONCRETE

Abstract

In present day Demolished Concrete waste handling and management is challenging one in all over the countries in the world. Recycle the Demolished Concrete has reduced the environmental pollution and protect the natural resources. This research is focused on utilizing the Demolished Concrete waste and reduces the generation of construction waste. This research included a collecting a Demolished Concrete from the demolition of building at site, Crushing Demolished Concrete waste and is separated with different sizes using sieve analysis. The Demolished Concrete Aggregate (DCA) is replaced by various percentages of 0 %, 25 %, 50%, 75 % & 100% adding with steel fiber, silica fume and test can be conduct and compared with nominal Concrete. Treated DCA with cement mortar and Super plasticizer (SP) admixture added to (1%) of total cementations materials (TCM). The concrete properties exams performed such as; density, compressive strength, splitting tensile strength, and Flexural strength test. The tests concluded that the compressive strength, splitting tensile strength and Flexural strength values of DCA concretes are reduced with an increased DCA ratio relative to normal concrete. DCA in the concrete mix as a partial substitute of gravel decreases the compressive strength about 26 %, 34 % at DCA 75%, DCA 100%, respectively, compared with the normal concrete. However, at (DCA50-Si-SP-SF1) (Mixing additives together), the compressive strength is increase up to 50 %. Adding SP on mix separately, it decreases the strength. But combine effect of SP & Si, SP & SF increases the strength up to 12- 14 %. The mix DCA 50 % Si 10% SF 1% SP 1% gives better Flexural strength on both 7 and 28 days as 3.92N/mm2 and 7.37N/mm2. The Flexural Strength was increased up to 34% at (DCA50-Si-SP-SF1) when mixing additives together.
