Experimental Investigation Concrete Using Magnesium Phosphate Cement, Fly Ash, and Rape Stalk
Publication: Journal of Materials in Civil Engineering
Volume 28, Issue 4
Abstract
This paper presents an investigation on a new material composed of magnesium phosphate cement (MPC), fly ash, and rape stalk. The main goal is to evaluate the viability of using this new material as an insulation material for buildings. Several composites with different weight concentrations and three different rape stalk sizes were prepared. The density, compressive strength, and thermal conductivity of the material were measured. Experimental results show that the proposed MPC rape stalk concrete possesses required material properties for production of lightweight concrete in structural and non-structural applications. The physical properties of the rape stalk indicate that it is a promising alternative to hemp hurd for producing plant concrete. Results also indicate that MPC might be a better cementitious material for producing plant aggregate concrete compared with portland cement or lime.
