Advantages of Precast Concrete Piles Advantages of precast concrete piles are as follows: 1. During concreting, the reinforcement which is used in the piles is not disturbed from its actual position. 2. Proper control in casting and curing can be exercised and if any defect after casting is noticed, it can be corrected before piles…

How To Prevent Concrete Deterioration? The following measures are taken to prevent deterioration of concrete: 1. From the consideration of permeability, the water-cement ratio is usually limited to 0.45 to 0.55. 2. The cement content should be such that it ensures sufficient alkalinity to prevent corrosion of reinforcement. For concreting under marine environment, minimum…
Causes of Deterioration of Concrete Deterioration of concrete is caused due to the influence of both external and internal agencies. The external or environmental agencies causing the deterioration of concrete includes: Weathering. Attack by natural or industrial liquids and gases. Acids in the form of water solution. Fertilizers, insecticides and certain organic compounds. Attack by…
8 Factors Influencing the Choice of Mix Proportions According to IS 456-2000 and IS 1343-1980, the designs of the concrete mix should be based on the following factors: 1. Grade Designation The grade designation gives characteristic compressive strength requirements of concrete. It is the major factor influencing the mix design. The concrete mix has to…
