What are the reasons to change strength with replacement quarry dust in cement plaster?
Best insight from top research papers
The change in strength with the replacement of quarry dust in cement plaster can be attributed to several factors identified in the research papers. Quarry dust, a by-product of crushing operations, offers potential as a substitute for sand in plaster production due to diminishing natural sand sources and cost reduction requirements . Studies show that partial replacement of cement with quarry dust in cement-sand mortar can lead to improved compressive strength initially at 5% replacement, indicating possible pozzolanic activity . Additionally, incorporating quarry dust in concrete mixtures at optimal percentages enhances concrete performance, with 25% quarry dust and 75% cement being identified as the best mix for standard strength and cost-effectiveness . These findings collectively suggest that quarry dust can positively impact the strength of cement plaster through its unique properties and interactions with cementitious materials.

Does XRD provide information about the crystallinity of plaster dust?5 answersXRD provides information about the crystallinity of plaster dust. The Rietveld method associated with X-ray powder diffraction (XRPD) data is efficient in identifying compounds in plaster dust that are not seen in thermogravimetric analysis (TGA). This method allows for quantitative phase analysis (QPA) to determine the amounts of each compound present in plaster dust. Additionally, a combined approach of scanning 3D X-ray diffraction and phase contrast tomography has been used to study the hydration of calcium sulfate hemihydrate to form gypsum, providing detailed crystallographic information on the transition observed in situ. Furthermore, pixelated energy resolving detectors enable acquisition of XRD signals, potentially paving the way for the development of novel benchtop XRD imaging or computed tomography (XRDCT) systems. Therefore, XRD is a powerful tool for studying the crystallinity of plaster dust and can provide valuable information for material analysis and characterization.
What is the influence of gypsum on cement?4 answersGypsum has a significant influence on cement. It can retard the setting time of hybrid alkali-activated cement (HAAC). The addition of gypsum affects the hydration behavior and strength development of belite-ye’elimite-ferrite (BYF) cement, with an optimal gypsum content of 18 wt%. Gypsum can also regulate the hydration reaction speed and optimize the compressive strength of Portland Composite Cement (PCC). In concrete with ground granulated blast furnace slag (GGBFS), gypsum can improve slump and compressive strength, with anhydrous gypsum producing higher optimum compressive strength compared to di-hydrate gypsum. Gypsum plays a vital role in the mechanical improvements of cement-based stabilized clay (CBSC), contributing to the formation of ettringite and pore infills, resulting in higher strength and a more homogeneous matrix.
Is gypsum amendment in clayey soil?4 answersGypsum amendment has been found to have significant effects on clayey soil. It has been observed that the addition of gypsum can modify the microstructure of the soil in an unsaturated state, reducing the vapour diffusion through the soil. Gypsum amendment has also been shown to reduce the losses of particulate and dissolved phosphorus (P) from agricultural fields, potentially providing an efficient means to reduce P losses from field cultivation. Additionally, gypsum amendments have been found to decrease turbidity, particulate phosphorus, dissolved reactive phosphorus, and dissolved organic carbon in soil over time. Gypsum applications have also been found to improve soil structure, increase aggregate stability, and increase porosity in clayey soils. Furthermore, the combined application of lime and gypsum has been shown to improve soil fertility, soil aggregation, and agronomic productivity in clayey soils.
What is the advantage and disadvantage of cement in dam?5 answersCement in dam construction offers several advantages and disadvantages. One advantage is that the use of low heat Portland (LHP) cement can decrease thermal stresses and cracking risk in dam concrete. LHP concrete also has better crack resistance and a denser pore structure compared to ordinary Portland cement (OPC) concrete. Another advantage is that cement-sand-gravel material, which is a low-strength and low-cost option, can be used for dam construction. However, there are also disadvantages. Fine aggregates with high water absorption can result in concrete with lower ultimate tensile strength and higher dry shrinkage. Additionally, environmental conditions such as temperature, wind speed, and relative humidity can affect the properties of dam concrete, including its resistance to chloride ion penetration and tensile splitting strength. Overall, the advantages of cement in dam construction include improved crack resistance and cost-effectiveness, while the disadvantages include potential issues with fine aggregates and susceptibility to environmental conditions.
What are the factors that affect the performance of bamboo as a reinforcement in cement concrete?5 answersThe performance of bamboo as a reinforcement in cement concrete is influenced by several factors. One factor is the modification of the bamboo surface using epoxy mortar (EM) and polyurethane (PE) adhesives, which improves the physical and mechanical properties of the bamboo aggregates. Another factor is the size and content of bamboo fibers added to the asphalt mastic, which enhance the high-temperature stability and low-temperature crack resistance of the asphalt. The addition of apus bamboo skin threads in petung bamboo reinforcement also increases the flexural strength of reinforced concrete beams. Additionally, the use of bamboo as a reinforcement material in building industries can reduce the cost and improve the structural strength of the concrete. Finally, the treatment of bamboo culms with seawater and mango polyphenol, as well as the curing age of the concrete, affect the flexural strength of reinforced bamboo with concrete infill.
What are the raw material factors affecting the performance of cement bricks?5 answersThe performance of cement bricks is influenced by several raw material factors. The addition of waste materials, such as brick powder, mining waste, fly ash, palm oil fuel ash, and vegetable particles, can have a positive effect on the properties of cement bricks. Brick powder can increase the silicon/calcium ratio and improve durability. Mining waste can increase the density of cement bricks. Fly ash and palm oil fuel ash can satisfy load-bearing requirements and reduce the Ca(OH)2 content. Vegetable particles, such as rice husk, can affect the mechanical and thermal properties of bricks, including density, water absorption, porosity, compressive strength, and thermal conductivity. These raw material factors play a crucial role in determining the performance of cement bricks and offer potential for cleaner production and environmental sustainability in the construction industry.
