A concrete saw is a power tool used for cutting concrete and masonry materials with abrasive or diamond blades. It can be hand or walk-behind operated and powered by electricity, gasoline, air, or hydraulics. It is designed for dry or wet cutting and is useful for commercial and home renovations. Different types of concrete saws […]
Concrete is a versatile and inexpensive building material, but builders need formwork to hold its shape as it dries. Formwork can be made of wood or metal and is constructed by formwork carpenters. Permanent formwork made of galvanized steel can add strength to the structure and reduce the need for rebar. Walking through any neighborhood […]
Mixing concrete correctly is crucial for a solid foundation. Purchase cement, sand, aggregate, and a measuring bucket. Use a cement mixer for a thorough mix. Add water equal to 55% of the cement used, and perform a slump test. Spread the concrete immediately and cover with moist tarps for 28 days. Concrete is often used […]
Proper concrete repair requires seamless bonding of new and old concrete. Use a cement compound and appropriate gravel, sand, and Portland cement. Apply a thin layer of cement paint and metal primer to prevent rusting. Finish by driving gravel below the surface and keeping the patch moist for at least a week. Quality concrete repair […]
A concrete gun uses compressed air to project cement or concrete at high speed onto building surfaces. It has two basic processes: dry and wet applications. The process is flexible and used in construction projects ranging from high-rise buildings to swimming pools. Cement spraying applications fall into two categories: dry mixing and wet mixing. Both […]
Modular concrete is cast offsite in a reusable mold, then cured in a controlled environment to ensure quality and durability. It is cost-effective and widely used in architectural structures and sewage drainage. Its high strength and low cost make it popular for various applications, including stormwater drains, foundations, and agricultural and paving purposes. Also known […]
Concrete shell structures are made of steel-reinforced concrete and have been popular since the early 20th century. They can be elaborate or utilitarian and require careful design for weight distribution, durability, and stability. The style declined in popularity due to changes in architectural style and rising steel costs, but new technologies may make them more […]
Concrete plugs are used to create a watertight seal in wells, damaged sections, or around supports. Cement grout is used to create additional strength. They can be used to close old water wells or seal off oil wells. They can fail under certain circumstances, requiring restoration. Concrete plugs are sections or portions of concrete that […]
Concrete stamps add decorative or natural patterns to wet concrete, creating a custom look for patios, driveways, and more. Color and hardeners can enhance durability and create a variety of natural surfaces. Embossing skins and stencil overlays offer alternatives. Concrete stamps come in various designs and sizes, and can be custom made. They provide an […]
Adding nano-platelets from carrots and sugar beets to concrete can improve its strength and reduce the need for Portland cement, which is not environmentally friendly. These plant-based mixes also outperform traditional additives and may require less concrete, helping to reduce emissions from the manufacturing process. Concrete has been used as a building material since ancient […]
Concrete sealer prevents water and other liquids from penetrating concrete, extending its life. Acrylics are cheaper but break down quicker, while solvent-based sealers are more expensive but last longer. Breathable sealants are better in freezing temperatures. The sealer can be applied with a sprayer or roller and comes in different colors. Appearance is secondary to […]
Concrete testing is essential for ensuring quality control and compliance with safety standards. Tests can be performed on site or in the laboratory, including the classic slump test. Laboratory analysis confirms concrete components and properties, necessary for high-stress projects. Falsified test results are a concern, and reputable companies use third parties for neutral results. A […]
Choose a concrete pump truck with the right capacity and pumping speed for your needs. Consider tire size, ease of use, boom length, and power. Some models can also lift mud. The best concrete pump truck will carry the amount of concrete you need and be able to access the areas where you want to […]
Concrete Canvas is a British brand that offers a “building in a bag” concept, using concrete cloth that only needs air and water to build. It is durable, affordable, and useful in disaster areas, refugee camps, and war zones. The product takes only 12 hours to build and offers more protection than tents. The developers […]
Concrete bridges are structures made of concrete that allow vehicles or people to cross physical obstacles. Concrete is versatile, strong, and requires less maintenance than other materials. Prestressed concrete bridges use reinforcing bars to counteract stress. Concrete arch bridges use a curved arch as the main support mechanism. High-performance concrete can be used for bridge […]
The myth of the mob using concrete shoes as a method of execution is unfounded. Concrete has been used in body disposal, but not as a method of execution. The term “cement shoes” is technically incorrect, as cement alone is unlikely to be used in body removal. The alleged victims are sometimes said to be […]
Concrete masons mix, pour, set and finish concrete or concrete blocks in the construction industry. They can acquire skills through on-the-job training or attend a professional education program. Apprenticeship programs require classroom training and work experience, and additional courses can lead to management positions. Good physical condition, reliability, and teamwork skills are essential. Certification is […]
Concrete inspectors ensure correct concrete type, depth, mix, and reinforcements are used, and that final work meets code requirements. Education, experience, and certifications are required. Inspectors must understand curing strength and weather effects. Jobs are available in various industries and locations. A concrete inspector performs a variety of tasks during construction projects. Inspectors verify that […]
A concrete mason builds structures using cement, pouring, smoothing, finishing, and coloring concrete. They create forms to contain wet cement, level it, and remove excess with trowels. Most work for municipal government organizations and construction companies, but some operate their own contracting businesses. They must be physically fit and have strong problem-solving and communication skills. […]
A concrete technician oversees the use of concrete in various applications, conducting lab experiments, overseeing pouring processes, and inspecting finished products. Education and training are required, including math and science skills, knowledge of the construction industry, and familiarity with new technologies and techniques. The technician must ensure the finished product is strong and free of […]
