Overview

Alkali-activated material, also christened as ‘Geopolymer’ is an innovative cement-free material that uses by-products and waste materials as replacements for cement. In this innovative construction of a geopolymer concrete house for the Universiti Malaya bus drivers, locally available materials such as Fly ash (FA), Ground granulated blast furnace slag (GGBS), and Palm oil fuel ash (POFA) were used as binders; these binders were activated using alkali activators. M-sand (Manufactured sand) was used to replace conventional mining or river sand. Palm oil clinker (POC), and steel slag aggregates (SSA) were used to replace conventional coarse aggregates.     

The primary objective of this research is to provide a viable alternative technology using locally available sustainable materials to replace cement, sand, and coarse aggregates. The prefabricated modules for wall panels, bricks, blocks, etc., were envisaged by replacing conventional construction materials using agro/industrial by-products. It is hoped that the cementless concrete products and demonstration of the geopolymer house constructed using sustainable materials will provide insight to developers, contractors, the public, students, academics, and researchers. 

Grade 40 geopolymer concrete was used for the cast in-situ concrete in columns and beams. The use of an Industrial Building System (IBS) by unique interlocking system of wall panels, is one of the salient points of the project. The development of Universiti Malaya Blocks (UMB) for interior walls is an important aspect of this project. Further, POC as coarse aggregates, a lightweight palm oil waste product, has reduced the weight of the concrete and the UMB.

Another prominent aspect is using recycled plastic aggregates in the geopolymer concrete pavement on all three sides of the house. 

Note: Those interested in visiting the 'Geopolymer House' built in UM can visit the house between 5.30pm and 6.00pm before the event starts.
