Groundnut shells did not improve strength or modulus compared to pure gypsum whereas a 35% higher strength was noticed with the addition of 10% coir. Hence, hybrid gypsum composites containing both shells and coir were developed leading to better properties than pure gypsum and commercially available gypsum boards.

14.1. Introduction. About 100–200 million years ago, the mineral gypsum (calcium sulfate dihydrate [CaSO 4 ·2H 2 O]) became precipitated as a result of the evaporation of seawater. It is deposited in sedimentary layers in the marine environment. Under high pressure and temperature, gypsum is transformed into anhydrite (CaSO …

Waste gypsum is an industrial solid waste which can be divided into three major categories: phosphogypsum (PG), flue gas desulfurization gypsum (FGDG) and red gypsum (RG). The main component of waste gypsum is CaSO 4 ·2H 2 O with a theoretical CaO content of 32.6 wt% which can store roughly 0.26 kg/ton of CO 2.
