produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an aggregate suitable or unsuitable for use in concrete. The ...
Special tests on core after crushing for strength: Sulphate attack, Cement and other minerals and mineral phases, and molecular groupings such as NaCl, CaCl 2, SO 3, C 3 A etc., Contaminants, Chloride attack, High alumina conversion, Aggregate reactivity. Advertisements Core should be taken to avoid reinforcements.
· Shorten the setting time of concrete, improve the early strength. It is common to use sodium sulfate (mixed with 2% of the amount of cement) and compound early strength water test admixture (mixed with 5% of the amount of cement). Fifth, choose aggregates with high particle hardness and few voids.
