How effective are plastic materials in improving the permeability of concrete for sustainable drainage?4 answersPlastic materials have been found to be effective in improving the permeability of concrete for sustainable drainage. The addition of polymer modifiers, such as styrene-butadiene rubber latex, polyacrylic ester emulsion, and organic silicon waterproof agent, significantly reduces the permeability of concrete. The use of waste plastic fibers as reinforcing materials in concrete also improves its impermeability, with an optimum volume fraction of up to 0.5%. Furthermore, the addition of nanosilica to plastic concrete mortar enhances its mechanical properties and permeability against sulfate attack, reducing the permeability coefficient. These findings suggest that plastic materials can be utilized to enhance the impermeability of concrete, making it more suitable for sustainable drainage applications.
Can polypropylene be used in concrete to reduce shrinkage?4 answersPolypropylene fibers can be used in concrete to reduce shrinkage. The addition of polypropylene fibers to self-consolidating concrete (SCC) mixes reduced the cracking area by 33%. Textile sludge, which contains polypropylene fibers, when used as a replacement for cement in concrete, decreased drying shrinkage due to its denser microstructure. In 3D polypropylene fiber reinforced concrete printing, the use of polypropylene fibers improved the resistance to cracking and resulted in low shrinkage. The incorporation of polypropylene fibers in ultra-high-performance concrete (UHPC) decreased autogenous shrinkage and reduced the cracking potential under restrained conditions. The use of polypropylene fibers in concrete has been shown to improve tensile strength, decrease elastic modulus, and reduce shrinkage-induced stress. Therefore, polypropylene fibers can be an effective solution for reducing shrinkage in concrete.
How does the addition of admixtures affect the properties of concrete?4 answersThe addition of admixtures in concrete has various effects on its properties. Mineral admixtures such as silica fume, fly ash, metakaolin, and ground granulated blast furnace slag improve the microstructure of concrete, leading to enhanced mechanical and durability properties. Waste materials like waste glass powder, rubber waste, and silica fumes can be used as concrete ingredients to form sustainable concrete, which may alter its properties in both positive and negative ways. Permeability-reducing admixtures (PRAs) and various cement dosages can be used to produce concrete mixtures with improved workability, compressive strength, and resistance to water penetration. The addition of type D and F admixtures can enhance the compressive strength of flowing concrete, while a combination of these admixtures may reduce its strength. The incorporation of fly ash and polypropylene fibers as admixtures improves the mechanical properties of concrete, but the corrosion rate of steel reinforcements may increase in certain conditions.
What are the best practices for ensuring drug container compatibility?4 answersContainer-content compatibility studies are important for ensuring the quality and safety of pharmaceutical drug products. The evaluation of the container-content relationship should consider factors such as the type and properties of the contact material, manufacturing processes, and formulation components involved. Stability studies are performed to assess the quality of the product, while toxicity testing, specifically cytotoxicity testing, is used to evaluate safety. Migration tests can be conducted to identify any interactions and select new materials if needed. A decision tree based on the toxicity aspect is proposed to support the container-content interaction approach and filing. The selection of containers should be guided by a quality-by-design approach, linking the properties of containers with the properties of drug products. This approach can increase efficiency and reduce costs in product development and can be used to evaluate the effectiveness of new containers.
Does silane coating improve the compatibility between polymer organic fiber and inorganic concrete?5 answersSilane coating has been shown to improve the compatibility between polymer organic fiber and inorganic concrete. In the study by Feng et al., the use of silane coupling agent (KH570) modified the interfacial transition zone between rubber and cement, strengthening the bond between the cement, rubber, and PVA fibers. Similarly, Liu et al. found that applying silane coupling agents (SCA) coating to the surface of polyethylene (PE) fibers enhanced the interfacial bonding and improved the mechanical properties of PE fiber reinforced cementitious composites. Furthermore, Gao et al. demonstrated that coating foamed concrete with silane-based emulsion reduced water absorption, improved anti-icing properties, and created a self-cleaning effect. These findings suggest that silane coating can effectively enhance the compatibility between polymer organic fiber and inorganic concrete, leading to improved performance and durability in various construction applications.
What is concrete retarder admixture philippines?5 answersConcrete retarder admixture is a substance added to concrete to delay the setting time and reduce the rate of strength development at early ages. It is used to improve the workability of concrete and prevent cracking caused by the heat released during hydration. The use of concrete retarder admixture can also reduce the amount of cement needed in the concrete, resulting in cost savings. Different types of concrete retarder admixtures have been developed, including those made from sodium lignin sulfonate, slag, sucrose, disodium hydrogen phosphate, magnesium sulfate, organic acids, vinyl acrylate copolymer emulsion, aminotrimethylene phosphonic acid, and glyceride. Other retarders may contain zinc sulfate, sodium hexametaphosphate, calcium carbonate, ethylene diamine tetra(methylene phosphonic acid), bone glue, glycerol, sodium gluconate, tourmaline powder, water reducer, dispersant, and surfactant. Oligosaccharide, propylene glycol methyl ether acetate, ethylene acrylate copolymer emulsion, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, ammonium acrylate, sodium pyrophosphate, sodium tripolyphosphate, and water are also used as cement concrete retarders. Additionally, molasses has been found to be a suitable retarder admixture for concrete, as it can delay the setting time and enhance the compressive strength at later ages.
