Stone powder cement (SPC) is widely used as a novel cement substitute material in concrete for its good gelling performance and low cost. In order to reduce the backfilling cost and assess the potential of SPC backfilling materials, a series of experiments were conducted to analyze the strength and hydration reaction mechanism of stone powder
Raw materials of MSC were the ordinary silicate cements, the admixture consisted of fly ash, slag and silica fume, the crushed stone and the manufactured sand. The cement’ compressive strength and tensile strength at 28 days ranged in 35.5–63.4 MPa and 6.9–10.8 MPa, respectively. The maximum grain size of crushed stone ranged from
The rheological properties of cement mortars and concrete mixtures are positively influenced by the addition of marble dust [10] and limestone powder [11]. Compressive strength of cement mortars and conctrete increases with the addition of granite powder [12] and basalt powder [[13], [14], [15]]. The dispersion component fills the space
The images of Control concrete, Besai stone dust concrete, Nowshera stone dust concrete, and Dara stone concrete are shown in figure 23 (1–4). Considerable reduction takes place in pores with the substitution of stone dust as curing time reaches 28 days and as a result, the mix is denser and attributing more strength.
The raw materials used to produce the mixtures were: Portland cement CP III 40RS, with 40 MPa of compressive strength at 28 days and a density of 2.98 g/cm³; natural and manufactured (crushed stone powder) sand; coarse aggregate with a maximum diameter of 25 mm and a density of 2.78 g/cm³; a plasticizer, FK 300 Muraplast (manufactured by MC

In this study, fine stone powder (FSP) generated in the process for producing crushed coarse and fine aggregate was used as a partial replacement for the fine aggregate. The durability of mortars was investigated under sulfate attack in terms of compressive strength loss, change in mass, and expansion. Cement mortars were made

Stone dust was acquired from three different sources i.e. Nowshera, Dara, and Besai, while concrete was kept at a ratio of 1:2:4 and water to cement ratio at 0.5 as per ASTM standards for considerable workability.
Pumice stone is a natural spongelike lightweight aggregate formed during the rapid cooling and solidification of molten lava. After suitable preparation, it can be used as an aggregate to produce lightweight concrete or as a cementitious material to produce blended cement or geopolymer. This article focused on the influence of pumice powder
The compressive strength of concrete from stone powder shows 14.76% higher value than that of the concrete made of normal sand. On the other hand, concrete from brick chip and stone powder produce higher compressive value from that of brick chip and normal sand concrete.
