Recycled Aggregate Concrete Performance

RESULTS OBTAINED IN VARIOUS FACTORIES IN THE MANUFACTURE OF CEMENT PLASTICIZED WITH CALCIUM LIGNOSULPHONATE ARE GIVEN. THOSE RESULTS SHOW THE NEED FOR (1) ACCURATE DEVICE FOR PLASTICIZER PROPORTIONING, AND (2) CLINKERS WITH A MINIMUM CONTENT IN ALUMINA AND TUCALCIUM ALUMINATE (AT LEAST 7 TO 8%). IF THE ABOVE CONDITIONS ARE NOT FULFILLED PLASTICIZED CEMENT WILL NOT REACH REQUIRED STRENGTH.
