Description Sulphate-resistant cement is recommended to be used in concrete exposed to severe sulphate action. It is advised where soils or ground waters have high sulphate content and it is also very suitable for foundations in all types of soils. The high sulphate resistance is attributed to low tri-calcium aluminate (C3A) content. Standard Specification It

Abstract The use of steel to reinforce concrete has been a long tradition, which is made possible by its strength and compatibility with concrete. Steel is also considered an ideal material for carrying out seismic-resistant construction due to its ductility and high-energy-absorption capacity. Raw materials from different sources are used in the manufacturing of steel
The 5th International Conference of Euro Asia Civil Engineering Forum (EACEF-5) Abstract Steel has been used for many decades in structural applications because of its good combination of mechanical properties. As per recent concept to reduce steel consumption in reinforced cement concrete (RCC) structures, designers recommend high strength steel bars. There are various routes for
Bricks used for construction should be of good quality.Good quality of bricks shall have following properties 1. Good compressive strength 2. Low efflorescence 3. Uniform size, shape and colour 4. Low water absorption 5. evenness of baking Unless used for load bearing structures, following quick site test generally used to check the quality of bricks. 5
Curing of concrete – an introduction Presence of water is important to complete chemical reaction between cement and water. The setting and hardening of concrete largely depends on presence of water for hydration process. While mixing the required quantity of water is generally added to concrete ingredient and theoretically no additional water is required.
Physical properties of 53 grade cement as per IS 12269 Portland cements are commonly characterized by their physical properties for quality control purposes. Their physical properties can be used to classify and compare Portland cements. The challenge in physical property characterization is to develop physical tests that can satisfactorily characterize key parameters. IS 12269 describes
Selecting right type of concrete pump using nomograph One of the major requirement of concrete pumping is to find out suitable pump for particular job. For right type of pump selection using nomograph, following information should be known 1.Require voulme of concrete to be delivered in hours (Cumtr / Hr) 2.Internal diamtere of pipe line
8 steps guide to determine the initial and the final setting time of cement as per IS: 4031 (Part 5) Materials and apparatus required : 1. Vicat apparatus conforming to IS: 5513 2. Balance, whose permissible variation at a load of 1000 gms should be +1.0 gm 3. Gauging trowel conforming to IS: 10086 4.
The building material “concrete” has the vastest utilization world wide. The performance of concrete have continuously rise in order to accomplish the society needs. This fact leads to obtaining an economic cost of product on short and long periods. Thus an innovative concrete “self compacting concrete” was found that does not require vibration for placing
