“…However, it was clearly proved that the additional C-S-H gel formation during the hydration of setting properties, which react the bonding/binding the cement with foundry sand. [17][18][19][20][21] concluded that the experimental test results produced the good strength improvement and also long term performace in durability studies showed a less chloride ion penetration of low permeability of averaged coulombs was noted 750 coulombs at 90-days and 365-days 500 coulombs in accordance with ASTM C1202-97.…”

 Abstract: The study focused on the effect of marble dust 0-10% (MD) by weight of cement content, waste foundry sand 0-30% (WFS) replaced by normal river sand and inclusion of glued steel fibres 0-1.5% (GSF) by volume fraction and also 1.5% of chemical admixture(SP) by weight of binding materials produced the excellent quality of structural concrete. Conversely, the replacement level of WSF can be limited up to 30%, Further, add into the concrete will affect the strength. From the test results observed that the 10% of MP, 20 % of WFS with 1.5% of GSF along with 1.5% of SP in concrete produced the higher compressive strength was 34.20, 39.90 and 42.50 N/mm 2 at 7, 28 and 56 days respectively, the strength was increased up to 7.40% than compared to controlled concrete. Also, a higher amount of bending stress was measured from 3.30 to 4 .57 MPa at 28 days for various mixes of concrete and the ultrasonic pulse velocity values are recorded between 3630 to 4030 m/sec for various mixes at 28 days. Finally, the durability measurement of RCPT and also material characteristics test on the modulus of elasticity of concrete were studied systematically.

“…Powdered carbonaceous rocks and shells are commonly used as soil amendments (Barros et al, 2009;Remonsellez et al, 2017;Holland et al, 2018;Ratke et al, 2018). One of such amendments is the marble powder that is generated as an industrial byproduct that results from the mining, sawing, shaping and polishing of marble (Brown et al, 1959;Ashish, 2018;Khodabakhshian et al, 2018). Using marble powder as a soil amendment also offers a solution of the environmental problems related to marble industrial waste disposal (Wang et al, 2017;Ashish, 2018).…”

Marble powder is one of carbonate rock amendments that is used to improve soil reaction. We hypothesized that the powdered marble addition can cause favorable changes in hydraulic properties of sandy soils. Six levels of marble powder addition to an aridisol soil (0%; M0; 5%; M5; 10%; M10; 15%; M15; 20%; M20 and 25%, M25; by bulk volume) were analyzed in triplicate. The saturated hydraulic conductivity and soil water retention curves were obtained. Pore space properties were investigated using soil water retention curves, mercury intrusion porosimetry and scanning electron microscopy. The saturated hydraulic conductivity significantly decreased (between 83 and 97% for M5 and M25 respectively) and parameters α and n of the van Genuchten model significantly decreased in marble-amended soils. Both field capacity and permanent wilting point increased with the addition of marble powder. Plant-available water, increased significantly until 10% of marble powder application; higher percentages of application did not provide additional significant changes in the plant-available water. Pore space distributions from soil water retention curves parameters showed an increase in the pore size range and a decrease in the average pore size; pore space distribution from the scanning electron microscopy also showed the presence of a new family of dominant pore sizes which was not detected by the soil water retention curves parameters approach. It was concluded that the addition of marble powder can improve the ability of soil to store water providing an advantage for irrigation water management in water scarce environments. Further research will have to address the impact of marble powder amendment under field semi-arid conditions.

In the marble industry, a lot of marble is wasted in the form of odd blocks of various sizes and slurry consisting of water and micro-fine particles. The slurry on drying converts into powder. Both slurry and powder have adverse effects on the environment. This research is focused on the gainful utilization of waste marble powder (WMP) by converting it into a valuable binding material. For this purpose, WMP and clay were collected, and their physical and chemical properties were determined. A mix of WMP and clay was prepared and burnt at a temperature around 1300 oC. The burnt mix was ground to powder form to get marble cement (MC). The MC was then used in mortar. The compressive and flexural strengths of mortar cubes and prisms were determined. Apart from this, X-ray diffraction (XRD) analysis, thermo-gravimetric analysis (TGA) and scanning electron microscopic (SEM) analysis were also carried out. The chemical composition showed that the MC has 52.5% di-calcium silicate (C2S) and 3.5% tri-calcium silicate (C3S).The compressive strength of MC mortar after 28 days curing is 6.03 MPa, which is higher than M1 mortar of building code of Pakistan (5 MPa). The compressive strength of MC mortar after one year is 20.67 MPa, which is only 17% less than OPC mortar.
