Civil Engineering Learning Platform: From Theory to Construction Practice
Concrete Technology covers the concrete properties, production, testing, quality control, and application of concrete in construction projects. This category includes concrete mix design, concrete grades, cube casting procedures, slump tests, compressive strength tests, curing methods, admixtures, workability, durability, and other essential topics related to concrete construction and quality assurance.
Learn pumped concrete mix design with aggregate proportioning, pumpability adjustment, workability, superplasticizer, pipeline considerations and practical trial pumping.
Learn how to use fly ash, GGBS and silica fume in concrete mix design, including SCM percentage calculation, code checks, absolute volume and practical trial-mix considerations.
Cementitious material content is one of the main calculations in concrete mix design. Once the preliminary free-water content and the adopted water-cement or water-cementitious materials …
Superplasticizer is one of the most important chemical admixtures used in modern concrete mix design. It can help obtain the required workability at a lower …
Learn how to calculate moisture correction in concrete mix design using aggregate water absorption, SSD condition, actual moisture content, corrected aggregate weight and batch water.
Learn the concrete trial mix procedure as per IS 10262:2019, including Trial Mix No. 1 to 4, workability checks, moisture correction, adjustments, cube testing and field approval.
Learn which cement, aggregate, water and admixture tests are required before concrete mix design, and which test results are directly used in mix calculations.
Learn how to select the water-cement ratio in concrete based on strength, durability and exposure conditions, with formulas, IS 456 limits, examples and practical mix-design guidance.
Learn how to calculate target mean strength of concrete using f′ck = fck + 1.65S and f′ck = fck + X, with standard deviation, X values and worked M10–M60 examples.
Introduction The core test of concrete is a method used to assess the compressive strength of hardened concrete by extracting cylindrical specimens directly from an …
