Previous studies have utilized marble dust as a replacement of cement, fine aggregate, or total paste in the concrete and mortar mixtures. In general, several investigations have shown that up to a certain cement replacement ratio, marble dust can positively impact on the strength and microstructure properties of concrete.
The production process for cement is a mix of traditional chemistry and hitech equipment Cement is a hydraulic bonding agent which is obtained by heating then grinding a mixture of limestone and clay Most cements are made from clinker and additives and are usually used in the form of a powder Cement sets when mixed with water ... 6 Ways to Use ...

Table 2 Chemical Properties of Marble Dust Powder - "SALVAGE OF CERAMIC WASTE AND MARBLE DUST FOR THE REFINEMENT OF SUSTAINABLE CONCRETE" ... Utilization of waste marble dust as an additive in cement production. H. Y. Aruntas, ...
It has been observed that setting period is reduced in a study that ceramic, red clay brick and concrete waste were used for 10% cement production [ 26 ]. Waste marble powder was mixed with cement clinker at different ratios (2.5, 5, 7.5 and 10% by weight) for cement production.
Waste marble dust has been used as an additive material in blended cement for cement manufacturing [13]. Most of the studies have focused on the replacement of marble dust with cement in the cement mortar [12]. SEM test was conducted on the mortar sample. Optimum percentage of marble dust in concrete was not defined.

The utilization of marble dust reduces the cost of cement-based material production and also decreases the costs of removing it from the environment [16]. The possibility of using waste materials such as marble dust as a partial substitution in the production of mortar and concrete has often been investigated by researchers [5,17-29]. Its ...
The aim of this study is to assess the possibility of utilizing waste marble dust (WMD) as a partial cement substitution in air-cured mortar (ACM). Three different levels of cement replacement were analyzed: 5%, 10% and 15% by cement weight. The specimens were manufactured in a local laboratory at an air temperature of 22 ± 2 °C and a humidity equal to 20 ± 1%.
How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
