Concrete and aggregate testing from SGS – helps you ensure that the quality of your concrete and aggregate complies with compulsory regulations and quality control standards. Concrete and aggregate used in your construction projects has to meet strict regulations and quality standards. As these standards are often compulsory, concrete and

 · Aggregate crushing value (ACV) provides an indication of the aggregate strength. Aggregate with lower ACV is recommended to ensure that the aggregate will be able to resist applied loads. The test was conducted on coarse aggregate of different grades. The ACV is calculated as the ratio between the weight passing sieve and the original weight. Values …

Other than AIV test, state two test to determine strength of aggregate.-Aggregate Crushing Value Test. Abrasion Test; Soundness Test; CONCLUSION. From the experiment, we get the value is 21% and 9 % less than the requirement concrete used for wearing surface such as road work which is 30 %. Aggregate physical property must lower Aggregate Impact Value, AIV …
