Limestone Powder. Calcined Clay. Slag. Green Mortar. Ternary Cement. Sustainably


The accumulation of massive waste has impacted human health and the city's appearance. As a result, there was a need to reduce waste by using by-products from industrial waste to replace cement, such as limestone, fly ash, silica fume, steel slag, and other minerals known as supplementary cementitious materials are produced environmentally and sustainably. This paper's purpose is to design a green mortar with the highest possible replacement of cement that has acceptable fresh and hardened characteristics. In this paper, three (SCMs), such as limestone powder (10%), calcined clay (0–35%), and slag (0–30%), were used to prepare ternary mixtures. The materials used in this research are available locally in Mosul, Iraq. The experimental studies were carried out for twelve mixes. The tests of flowability, flexural strength, compressive strength, dry density, ultrasonic pulse velocity, and water absorption on green mortar have been conducted. The cement was replaced 30% to 60% with a combination of ternary cement containing calcined clay, limestone, and slag in different replacement percentages than in other green mortar mixes. The results found that replacing OPC (30%), which contains 10% limestone, 10% steel slag, and 10% calcined clay, gives the highest compressive strength and flexure strength enhancement, which are 24% and 18% greater than the plain mortar after 28 days. When cement replacement was increased for ternary mixes, the result differed slightly from the plain mortar. Water absorption increased as the SCMs were increased. Dry density showed little effect.
