Experimental study on mortar as partial replacement using sawdust powder and GGBS

Increasing demand and depletion of natural resources in construction world, so we need for the replacement of conventional mix. In this project main objectives is the sawdust powder 5%, 10%, 15% partially replaced by fine aggregate and the cement mortar consists of ordinary Portland cement with 10%, 20%, 30% partially replacement by ground granulated blast-furnace slag. Then add superplasticizer water reducing admixture very high workability and strength. Use of sawdust powder in mortar permits disposal of waste (saw dust), reduce the weight of the concrete. Good thermal insulation, efficient energy and low cost of material. The experimentation will be performed for 1:4 cement mortar 0.45% water cement ratio at various temperatures 50 degrees c, 100 degrees c. Result was expected to be used low carbon materials and eco-friendly solution to wood waste recycling for the construction industry. (C) 2020 Elsevier Ltd. All rights reserved.

Automated summary

The study aims to reduce resource consumption in the construction industry by incorporating sawdust powder and ground granulated blast-furnace slag in place of traditional materials such as cement and fine aggregates, achieving the production of lightweight concrete and waste recycling.
