For producing high quality concrete you should take control of problems which are commonly occurred during concreting. These problems mainly happen for improper mixing, placing and handling. Some problems also happen due to weather effect and other reasons. These problems have major impact on strength and duration of concrete First you should know about the […]
To find : weight of steel per metre. Since the formula to be derived is d^2/162, assumed cross section is circular and the material is cylinder. Weight density of steel = 7850 kg/m^3. Rod Number Rod Size (in) Rod Weight (lb per linear foot) 2 0.250 = 1/4″ 0.17 3 0.375 = 3/8″ 0.38 4 […]
Foundation is a part of structure which interfaces the superstructure to the adjacent zone of soil or rock below it. The purpose of having a foundation is to transfer the superstructure loads to the underlying soil or rock without overstressing the soil or rock. Placing the footing at a sufficient depth that the soil […]

Concrete consists of different materials, which have different functions .The properties of concrete depends on the particular mixture of constituents. The basic constituents used to make concrete are cement, lime, water and aggregate. Do’s 01. Do hire an experienced contractor for successful concreting operation. 02. Also see that the main/general contractor hire good skilled sub/labour contractor […]
Lubricating nature of workable concrete is the most important nature. Workability is dependent on the proportion of the constituent material as well as on their individual characteristics. The factors that affect the workability of concrete are given below: 01. Water Content of the Concrete Mix Water content will have important influences on the workability in […]
Concrete Mix Design Mix Design It is a process of selecting suitable ingredients and determining their relative proportions with the objective of producing concrete of having certain minimum workability, strength and durability as economically as possible. Requirements of concrete mix design The requirements which form the basis of selection and proportioning of mix ingredients are : a […]

Lap length ( horizontal/vertical) Development length Covers for footing/column/beam/slab. 2. Calculate the cutting length of the bars. ( total length – covers on […]
Terrain and soil conditions, road standards, machine and labor costs etc. are considered as the prime factors which can change the road construction cost significantly. Besides, the skills of the associated operators and labors are also affected. As the road construction systems are identical all through the globe, one can effortlessly develop rational cost estimates […]
To determine an accurate building materials cost estimate, the estimator should take into consideration various factors. Different building components like roof, wall, floor etc.; items required like rebar, stud, paint, etc.; materials such as steel, pine, vinyl, etc.; the size and description of the items along with its estimated quantity and unit cost are […]
