Effect of the Partial Replacement of Cement with Waste Granite Powder on the Properties of Fresh and Hardened Mortars for Masonry Applications

Abstract

Granite is a well-known building and decorative material, and, therefore, the amount of produced waste in the form of granite powder is a problem. Granite powder affects the health of people living near landfills. Dust particles floating in the air, which are blown by gusts of wind, can lead to lung silicosis and eye infections, and can also affect the immune system. To find an application for this kind of waste material, it was decided to study the effect of partially replacing cement with waste granite powder on the properties of fresh and hardened mortars intended for masonry applications. The authors planned to replace 5%, 10%, and 15% of cement with waste material. Series of mortar with the addition of granite powder achieved 50% to 70% of the compressive strength of the reference series, and 60% to 76% of the bending strength of the reference series. The partial replacement of cement with the granite powder significantly increased the water sorption coefficient. The consistency of the fresh mortar, and its density and water absorption also increased when compared to the reference series. Therefore, Granite powder can be used as a partial replacement of cement in masonry mortars.

Physico-Mechanical Properties and Hydration Processes of Cement Pastes Modified with Pumice, Trass and Waste Chalcedonite Powder

“…The greater the amount of granite powder, the higher the adhesion of mortars. The positive influence of granite powder (in the amounts of 5% and 10% by mass) on consistency and water absorption was confirmed by Woźniak et al [32]. The replacement of cement with an optimum 10% content of granite powder reduced the mechanical properties of masonry mortars.…”

“…A good idea in the production of Portland cement with additions and low-clinker cements is the use of waste stone powders such as granite, marble, basalt or chalcedonite powder [ 15 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Abdelaziz M.A.…”

“…The grouting repair method is widely used in the repair and strengthening of existing concrete structures because of the advantages of good reinforcement effect, high construction efficiency, economy, and adaptability [15]. Specifically, inorganic or organic repair materials are injected into the defects of existing concrete structure, through the repair materials in the process of solidification and hardening of the physical-chemical effect on the existing concrete, so as to achieve the purpose of improving the load-bearing performance and service life of the existing concrete structure.…”

Impact of Superplasticizers on the Performance of Low-Grade Limestone-Based Cement Mixes

“…Some non-reactive or weakly reactive powders, such as marble [ 7 ], granite [ 8 ], and limestone [ 9 ], showed promising contributions. Among these cement replacement materials, limestone powder shows great potential due to its very low embedded CO 2 emission, abundant reserve on Earth, and low cost [ 10 ].…”
