aggregate crushing value limits for concreting

CHAPTER 4 MATERIALS INVESTIGATION AND MIX . MATERIALS INVESTIGATION AND MIX PROPORTION 4.1 GENERAL ... 4.3 FINE AGGREGATE The fine aggregate used in this investigation was clean river sand ... Crushing value (IS: 2386 – 1968 Part 4) 46 The results of the tests on coarse aggregate are given in Table 4.3. What is the effect of coarse aggregate size in compressive ... Larger the aggregate, greater is the tendency of blocking the bleed water and thus weaker is the transition zone (higher w/c ratio in area around the aggregate). This results in concrete cracking through the transition zone since both the other phases (aggregates and cement paste) are much stronger. Concrete lab s5 procedure - SlideShare AGGREGATE CRUSHING VALUE Experiment No: 4 Date: AIM:- To determine the aggregate crushing value of the given coarse aggregate. GENERAL: - The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.    Read More
