Compressive strength of laterite stone mixed concrete

Abstract

Abstract Concrete is one of the most durable construction material and cement is one of the most energy intensive structural materials in concrete. This research is conducted to research of the suitability of tap water, river sand and laterite stone which is available abundantly surround the Berau district of Indonesia with Portland composite cement (PCC) and crushed laterite stone to produce concrete. Test result exhibited that fresh concrete had proper workability and all hardened specimens appeared a good compaction result. This paper purposed to utilized tap water, river sand, laterite stone and Portland composite cement to produce the high performance concrete to eliminate the main problems of stone shortage and fine aggregate in the low land areas and the Berau district of Indonesia. Infrastructure development can be sustained through the effective use of available local materials surround the Berau district of Indonesia. The evaluation result on the workability of fresh concrete and strength development of hardened concrete were discussed.
