Strength and durability of concrete containing recycled …

2018-9-1 · Recycled concrete aggregate was produced from concrete waste sourced from the demolition site of a water tank. The core strength of the original concrete was found to be 25 MPa. The concrete waste collected was subjected to primary crushing and screened to control the particle sizes of the recycled concrete aggregate.

Improvement on strength and impermeability of recycled …

An increase of 30 and 15% in compressive strength at ages 7 and 28 days, respectively, is observed through pretreating the recycled aggregate with silica fume solution (10 wt%). 1 …

2017-11-15 · The concrete age coefficient is set to be a ratio of a certain concrete compressive strength and compressive strength at 28d. Table 6.1 shows the relative cube compressive strength with the different w/c ratio and the curing age ranging from 7 to 360 days. From Table 6.1 it can be seen that before 90d, the curing coefficient of NAC is lower than that of RAC, and …
