Abstract


The utilization of fly ash to produce green mortar (GM) is a successful approach to improve sustainability, decrease costs, and enhance some aspects of durability. However, green mortar with fly ash partially replacing the cement by weight often experiences low compressive strength at the early ages, which minimizes the material applications. Several tactics have been proposed to boost the compressive strength; some procedures are not economic, while others consume much energy. Enhancing the GM compressive strength through the adoption of reducing the water/binder ratio technique through the chemical admixtures addition can be considered a practical and economic technique. This study investigates the influence of the addition of chemical admixtures on the water content and the compressive strength of GM which is comprised of 70% cement + 30% fly ash. Two different chemical admixtures were used in this study; each one has a different chemical composition, which represents different generations of plasticizers. The first type commercially known as ViscoCrete-5930 is essentially composed of polycarboxylate, while the other type which is essentially composed of lignosulphonates called here as Flocrete SP90S. Both types were added to the mortar, individually and binary with a fixed dosage (2% of the binder by weight). Workability and mechanical properties up to the age of 28 days were recorded. The experimental results showed that both admixtures are capable of reducing the water/binder ratio by about 20%. The addition of 2% of ViscoCrete-5930 most efficiently increased the compressive strength by about 85%, 58%, 55% at 3, 7, and 28 days, respectively. The addition of lignosulphonate based admixture such as Flocrete SP90S to the GM for more than 1% is harmful to the GM in the hardened state and causes partial or severe deterioration during the hydration process. This study leads to a fact, that the compatibility of polycarboxylate based admixtures and blended cement containing a significant amount of fly ash, is significantly better than the compatibility of lignosulphonate based admixtures and blended cement containing the same amount of fly ash.
