Concrete is a strong, durable construction material that can be formed into whatever shape you need. It is made up of gravel, sand and rock that has been bound together by cement and water. The strength of concrete is influenced by the quality and distribution of the aggregate, the amount of water used and the curing method employed. Other ingredients can also enhance its performance, including fly ash, ground granulated blast furnace slag and silica fume. Precast Concrete In precast concrete construction, builders use concrete that is cast into structural members off-site and then brought to the construction site for installation. This method of building can increase the strength and finish durability of the concrete and reduce construction time and costs. It is especially useful for large-scale projects that require repeated elements like slabs, walls, and modular boxes. It is also ideal for applications where multiple identical concrete components are needed. This is because pre...

A slab is a shallow foundation that spreads the load imposed by a building over a large area. This reduces deflections and vibrations while providing fire protection and thermal storage. To check for proper formwork, stretch a string across the top of the forms and measure to the ground in three or four spots. Avoid hot and windy days; concrete hardens quickly in these conditions. Corrugated Slab The corrugated slab is a type of reinforced concrete slab that uses high-tensile steel tendons to reduce the load on the concrete. This allows the slab to have a greater capacity for resisting tensile stresses, and can help reduce deflections. This type of slab is often used in large buildings where space is limited, because it can be built more quickly than a traditional concrete slab. It is also more cost-effective than other types of slabs. This research aims to compare the flexural performances of conventional slabs with a new type of composite slab metal decking (SMARTDEK) made of 0....

Having a driveway can make it much easier to park your car and get in and out of the house. It also increases your property value and adds curb appeal to your home. Concrete driveways cost $4 to $15 per square foot and can be stained, stenciled, or etched for an extra design element. Adding a brick or paving stone border to the edges costs an additional $6 to $15 per linear foot. Curb Appeal A driveway is an important part of a home’s curb appeal. It’s where neighbors, friends and strangers alike first make their initial impression of your property. And while enhancing the exterior appearance of your home can seem like extra work at a time when most homeowners already have plenty on their plates, it’s well worth the effort for anyone who wants to attract a quality pool of prospective buyers and boost their property’s perceived value. A paved driveway can be made of asphalt or concrete, with prices varying depending on materials and installation requirements. Generally, asphalt wil...

Unlike traditional surface and clear coating systems which are expensive to install, require regular maintenance and eventually need to be replaced, hiperfloor is permanent. This significantly reduces life cycle costs, maintains the original concrete substrate and improves durability. Certified contractors working in conjunction with Husqvarna premium grinding equipment, diamond tooling and chemicals can radically transform new or existing concrete floors. The process mechanically refines the concrete surface through varied procedures achieving beauty, functionality and strength back by a 7 year warranty. Reduced Environmental Impact The HiPERFLOOR process is a green, sustainable solution to resurfacing and renovating your concrete flooring. It utilizes products that cause very little environmental stress and waste during application. It also eliminates the need for reapplications of topical coatings that can lead to flaking, peeling and delamination. The abrasion-resistant finish ...

Concrete can last a long time but if it gets old and starts to deteriorate due to design, workmanship or materials – it can be costly. Mechanical demolition has been the only way to get inside concrete but now epoxies and urethanes can be injected into cracks. This will repair concrete and maintain its properties. Crack Injection Crack injection, as the name implies, involves injecting epoxy resin into concrete cracks. The bond strength of fully cured epoxy is higher than the concrete tensile strength and therefore provides excellent crack sealing. Epoxy injection resins are formulated for various crack widths and viscosities, so it is important to use the appropriate formula for the crack you are trying to repair. The first step is to install injection ports, short rigid-plastic tubes with a flat base that serve as handy entryways into the crack. These ports should be spaced approximately an inch apart for every inch of wall thickness. Apply a thin coat of paste-over material arou...
