This includes slurries obtained from the quarrying, cutting and polishing of marble, which can be used as a source of calcium carbonate, alternative to primary limestone. This contribution illustrates the use of waste calcium carbonate, obtained from marble slurry (waste marble, WM), in sustainable cement materials alternative to Portland cement.
Is calcium carbonate used in concrete? Calcium carbonate, in the form of limestone, has seen an increase in its use as a cement additive to reduce the carbon footprint of cement clinker, which is due to the relatively low CO2output of the process in comparison to Portland cement manufacture [6]. What is the role of calcium carbonate in cement?
CaCO3 is a natural material, which has a finer particles size as compared to the cement particles. This improves particle packing of concrete and give spacer effect. The concrete with CaCO3...
Due to its unique properties, the calcium carbonate cement is well suited for building materials applications with controlled factory manufacturing processes that can take advantage of its rapid curing at elevated temperatures and lower density for competitive advantages.
Calcium carbonate concrete is made from waste concrete and CO2 from the air. How are these used to create this new building material? Concrete waste powder is put into water, and air bubbles are blown into this water to produce a calcium bicarbonate solution. The solution is flowed between the concrete waste particles in the container.
This contribution illustrates the use of waste calcium carbonate, obtained from marble slurry (waste marble, WM), in sustainable cement materials alternative to Portland cement. The possibility of exploiting locally available resources is explored, and the effect of WM additions up to 50% by total mass on the macroscopic properties is investigated experimentally.

This study investigated the limestone powder (LS) particle size effect on the heat of hydration of Portland cement (PC) and high-calcium fly ash (FA) systems. The LS used has a maximum particle size of 5 and 20 μm, respectively. Isothermal calorimetry was used to measure the heat evolution during the hydration process of the cement and PC–FA pastes.

It is also noteworthy that adding carbonate in the form of calcium carbonate to cement slightly reduces its buffering capacity towards subsequent carbonation, for example in atmospheric carbonation. If protection of embedded steel is important, it is desirable that improvements in cement performance, for example reduced permeability arising from calcite …
Traditionally carbonation curing of concrete was applied at high pressure (HP) in a pressure chamber with various duration and most of the results elucidated that the formation of calcium carbonates and their intermingling effect with C S H were the reasons for the strength gain and the enhanced properties of cementitious materials.
Calcium carbonate can be used as a filler in Portland cement, reducing the product's high cost. Calcium Carbonate's Contribution to Reduction of Carbon Imprint Approximately 8 to 10% of global anthropogenic CO2 emissions are produced by cement industries, and cement production is projected to exceed 6 billion metric tons by 2050.
