Oil palm shells (OPS) are mechanical waste that is utilized as coarse aggregates in lightweight concrete. These OPS have shape and strength like conventional aggregates yet the substantial made with these OPS invigorates a limit of 18 MPa. The characteristic strength which must be utilized in structures is seen to be around 25 MPa to 30 MPa. Considering the strength as one of the boundaries for design to be sturdy, the OPS are surface-covered with nanosilane compound. This nanosilane covering goes about as infill on the outside of the aggregates and holds the concrete paste as traditional cement. Operations are permeable in nature; their inner construction has permeable design which makes the aggregates frail. Nanosilane coatings go about as holding between the concrete stage and aggregate stage and hold the substantial solid. In the present examination, mechanical and underlying conduct of nanocovered oil palm shell lightweight concrete is contrasted with that of regular cement. Nanocovered oil palm shell lightweight substantial shows comparative strength as customary cement and decrease in nonsustainable wellspring of energy in oil palm shell lightweight concrete. Supplanting of customary cement with oil palm shell concrete addresses the modern waste which can be utilized for making concrete solid and solid. Morphology and material portrayal of oil palm shell and ordinary aggregates are investigated.

Coconut shell is a waste, generated by industrial and agricultural processes. The waste coconut shell is utilized to replace natural coarse aggregate. In this project, using coconut shell as a partial replacement of coarse aggregate. Making of cubes (150*150*150) and cylinders (150*300) by partial replacement of coconut shell as a coarse aggregate. Analyzing the compressive strength of concrete for M20 Grade concrete by using coconut shell as a substitute for conventional coarse aggregate with 10%, 15% and 20%of partial replacement. The tests on concrete can be conducted on 7,14, and 28 days. The main purpose of this research study was to observe the compressive strength of concrete with various properties of coconut shell.

India is one of the Developing countries that needs to face the environmental pollution. Have many ways to reduce environmental pollution that causes by production of Portland cement and cause by the increasing of waste material. This paper studies the strength development in geopolymer mortar using industrial by-products. Geopolymer is the term used to represent the binders produced by polymeric reaction of alkaline liquid with silicon and aluminium as source materials. The by-product materials considered in this study are combination of GGBFS and Fly ash. The experimental program involves casting of geopolymer mortar cubes and testing them at 1 day, 3 days and 7 days for compressive strength. Different parameters considered in this study are ratio of sodium hydroxide to sodium meta silicate (1:1 & 1:2 ) and alkaline fluid to binder ratio Keeping 12-Molarity of the alkaline liquid as constant. It can be concluded that the strength increased with an increase in the quantity of GGBFS.
