Modification of mixing process showed a positive influence on the properties of RAC. A new mixing method named two-stage mixing approach (TSMA) was proposed and showed a significant enhancement for compressive strength of RAC, especially for that at early ages and with high replacement ratio by RA.

This paper presents an experimental study to evaluate the influence of the water addition and pre-saturation of recycled aggregates (RA) on rheological and mechanicals properties of concrete. Quantities of water absorbed and their variations in times were measured according to the European standard (EN 1097-6). Two methods were tested: pre-saturate the aggregates and add them to other ...

Civil At Work: TWO STAGE MIXING APPROACH

Dec 31, 2017  The prerequisite in applying RA to high-grade concrete is to overcome these weaknesses. A new mixing approach, two-stage mixing approach (TSMA), is proposed. For NMA, the mixer is firstly charged with about one-half of coarse aggregate, then with fine aggregate, then with cement and finally with the remaining coarse aggregate.
