The National Water Resources Master Plan of Oman forecasts that the overall demand for water for domestic, industrial, …
When water is mixed to cement Aluminates and sulfates get react and evolve some heat but gypsum acts as coolant and brings down the heat of hydration. Gypsum cements possess considerably greater strength and hardness when compared to non gypsum cement. Water required in gypsum based cement for hydration process is less.
This study explores the mechanical properties, as well as the water-reducing and setting delay mechanism, of a novel xylonic acid-based water reducer applied to cementitious materials. Four xylonic acid water reducers were synthesized in this study: XACa (PX) from pure xylose, XACa (HS) from hemicellulose hydrolysate, XANa (PX) …
Gypsum plays a pivotal role in this aspect by improving soil structure and water retention. As soil quality is enhanced, it requires less irrigation to support crop growth.

2.1 Test Matrix. Five total mix designs are considered for this study including one control batch, two batches that involve fine gypsum as a partial replacement for cement in different amounts (20 and 10%), and two batches that involve the whole gypsum as partial replacements for 10 and 20% of cement in the concrete.
In addition to the cation exchange, the formation of cementitious hydration products such as (CSH) and (CAH) has also been reported in gypsum-treated clays (Latifi et al., 2018; Zha et al., 2021).The CSH and CAH can be produced through the pozzolanic reaction if the calcium from gypsum reacts with soluble alumina and silica from clay in …
In the production of gypsum board, water reducer plays the following important roles: 1. Reduce the amount of cement: water reducer can improve the fluidity and plasticity of cement paste, thus reducing the amount of cement. By reducing the amount of cement used, costs can be reduced and adverse effects on the environment …
Gypsum plays an important role in improving soil structure properties and soil will benefit from gypsum. In these areas soils can be saline or sodic. Salinity is the salt content in the soil and salts are the soluble nutrient ions in the soil solution and not on the soil's cation exchange complex.
