Solvent cement softens thermoplastic surfaces to form a strong solvent weld joint. Proper preparation and compatible cement are necessary for a strong bond. Ventilation is important due to strong fumes. Signs of bad cement include a gel-like consistency or lumps. Diluting or applying at incorrect temperatures will weaken the bond. The solvent cement welds the […]
Soil cement is a low-cost foundation made by mixing Portland cement, water, and soil aggregate. It’s suitable for road construction and can be made from various types of granular materials. The process involves mixing the materials on-site or at a mixing plant, compacting them, and applying a bituminous material for hardening and strengthening. Soil cement […]
Slag cement, a byproduct of iron production, is a consistent and eco-friendly material used in concrete. It improves processability, finishability, and strength while reducing permeability and greenhouse gas emissions. Slag cement has been used for over a century and is now widely available in the US. Recent manufacturing advances and terminal capacity expansion have led […]
Fly ash, a byproduct of coal burning, can be used as an alternative or supplement to traditional Portland cement in concrete. It is considered environmentally friendly and can reduce contamination, but there are concerns about potential health risks and lack of regulation. Limits have been set on acceptable levels of toxins in fly ash cement. […]
Fly ash concrete has advantages over regular concrete, including reduced water permeability and increased strength. Poorly produced fly ash has disadvantages, but properly manufactured fly ash produces a quality product. Fly ash fills small spaces within the mix for a cohesive substance that resists water infiltration and has a high strength. The slow curing time […]
Cementum is a yellowish layer of connective tissue that covers the root of a tooth, protecting it and helping to hold it in place. It is softer than enamel and dentin, and is constantly produced by cementoblasts. There are three types of cementum, and gum recession can expose it, leading to erosion and tooth loss. […]
Cement mills grind clinker, a hard material produced by sintering aluminosilicate and limestone in a kiln, into fine particles. Ball mills are the most common type of cement mill, using steel balls to crush and grind the material. High-pressure roller mills are occasionally used but less widely accepted. The main constituent of Portland cement is […]

To become a cement mason, enroll in an apprenticeship program or gain on-the-job experience as a mason’s helper. Physical labor is required, and masons shape and finish concrete by hand. Cement masons work on residential and commercial projects, including highways and public works. Most people who want to become bricklayers enroll in an apprenticeship program. […]
Cement industry jobs include bricklayers, finishers, and terrace finishers who use concrete to create structures like decks and patios. Workers may start in construction to learn the fundamentals and compensation is usually hourly. Masons guide the concrete laying process and contribute to the aesthetic finish. Jobs typically have 40-hour workweeks but may be delayed by […]
