Concrete Mix Design

A practical treatment of concrete mix design, covering material selection, design parameters, water-cement ratio, durability, target strength, aggregate proportioning, trial mixes, testing and quality control. Based on IS 456 and IS 10262:2019, it enables engineers and students to develop economical, workable, durable and structurally reliable concrete mixes with confidence. What's inside • Introduction and objectives of mix design • Properties and durability of concrete • Concrete grades and types • Constituent materials and mineral admixtures • Design factors, methods and the IS 10262 overview • Selection of water-cement ratio • Durability requirements as per IS 456 • Target mean strength and influencing factors • Air content, total and effective water content • Cementitious material and minimum cement content • Coarse aggregate proportion and grading • Mix proportions — volume calculations • Quality control, challenges and material properties • Worked example: test data, calculations and trial mixes • Sampling, slump, cube specimens and strength analysis
