    Circular Column Design

    Circular reinforced columns have higher strength than square or rectangular columns. Circular cross-section columns are more resistant to buckling as compared to a rectangular cross-section. Furthermore, circular sections will have uniform torsion characteristics. circular column design spreadsheet example The difference between the strength of two different types of columns: Columns having shear reinforcement in form of spirals gives better […] More

    3 Types of Concrete Joints in Building Structures

    Concrete joints are used to compensate when concrete expands or shrinks with changes in temperature. Concrete joints are normally used to prevent cracks when the concrete shrinks, by creating forming, tooling, sawing and placing joint formers. The pre-planned cracks will provide a better finish concrete product and will be formed in specific locations where those […] More

    Specification for Transporting and Placing Concrete

    Concrete drop during vertical placement shall not exceed 2.5m. For heights greater than 2.5m, the Contractor shall pour concrete through enclose chutes or access hatches, details of which shall be approved by the Engineer. This must comply with four main requirements, namely: It must be rapid so that the concrete does not dry out, lose […] More

    How to Control Concrete Waste at Site

    While estimating quantity of concrete for particular structural work, we normally consider 3-5% as wastage. But concrete waste more than that can increase the cost of project and may impact project progress. So, it is necessary to control the concrete wastage at site. Concrete wastage can be prevented by proper planning of pour. Concrete pour cards shall […] More

    Concrete Admixtures

    Admixtures confer certain beneficial effects to concrete, including reduced water requirement, increased workability, controlled setting and hardening, improved strength and better durability. Admixtures are materials other than cement, aggregate and water that are added to concrete either before or during its mixing to alter its properties, such as workability, curing temperature range, set time or color. Many […] More

    Concrete Curing Compound

    Concrete Curing is the process of controlling the rate and extent of moisture loss from concrete during cement hydration. The hardening is not due to drying. If concrete is allowed to dry soon, it results in poor strength and a porous material is obtained. More

    Strength of Concrete

    The strength of concrete depends upon the amount of cement content, quality and grading of aggregates, water of concrete ratio, compaction and curing Strength of concrete increase very fast in the initial stage. In the 7 days, the strength gained is as much as 60 to 65present of 25 days strength it is customary to assume […] More

    Fiber Reinforced Concrete

    Fiber reinforced concrete is concrete containing fibrous material which increases its structural integrity. Fiber reinforced cements and concretes are firmly established as construction materials.  Since the early 1960’s extensive research and developments have been carried out with FRC materials leading to a wide range of practical applications. In recent years, a great deal has been leaned […] More
