Effect of Soaps on the Properties of Portland Cement ...

20/10/2010  Calcium and sodium stearate soap additions in the ordinary portland cement have been studied by mixing 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 per cent respectively by weight of cement. Cement and sand mortar in the ratio of 1:3 with diiferent percentages of additives were tested for workability and water retention properties.

21/05/2014  Effect of lime addition on the properties of Portland cement has been studied by taking 1:9, 2:8, 3:7, 4:6, 5:5 and 6:4 lime/cement mixes. Setting time has been determined by taking neat cement and cement lime mixes. Workabilities, water retention values and strength have been determined by taking cement-lime-sand mortars. It was observed that lime acts as retarder and

30/11/2018  This study investigates the effects of replacing a portion of Portland cement with slag cement (0%, 25%, 50% and 65% by mass) on the properties of plain ultra-high performance concrete (UHPC) mixes. It is observed that slag cement substantially enhances the flowability of the UHPC mixes and reduces the superplasticizer dosage. Mechanical properties are evaluated for mixes with similar

17/08/2021  Cement is the most manufactured commodity worldwide and is essential to building modern infrastructure. The most ubiquitous cement is Portland cement (PC) that is produced in high-temperature kilns. The quality of PC relies on several factors including the chemical composition and physical properties of the raw materials, the type and composition of fuels used to supply heat to the

27 survey properties of cement throughout the southwest part of China and investigate their effects on 28 plastic cracking [13]. Chemical and physical properties of cements from 233 manufacturers were 29 examined and the primary results are given Figure 1. It can be seen from Figure 1 that around 86 % 30 of cements have a specific area varying from 320-360 m2/kg, with 9 % having an even higher ...

of Portland cement. In brief, Portland cement is produced by crushing and grinding calcareous materials (e.g. limestone, chalk) and argillaceous materials (e.g. clay, shale), as a wet slurry or in a dry state. The mixture is calcined in a rotary kiln and the resulting clinker is finely ground. The product is composed largely of calcium silicates, aluminates, and alumino-ferrites. Other ...

Effect of Cement Content on Concrete Performance

Of all the traditional concrete materials, portland cement has the greatest impact on mixture cost and the environment. Cement is in many ways the glue holding concrete together (Weiss, 1999), and as such, it plays a major role in fresh and hardened concrete properties.

The greater the percentage of GGBS, the greater will be the effect on concrete properties. Setting times. With GGBS, the setting time will be extended slightly, perhaps by about 30 minutes. The effect will be more pronounced at high levels of GGBS and/or low temperatures. An extended setting time is advantageous in that the concrete will remain workable longer and there will be a reduced risk ...
