EFFECT OF POLYCARBOXYLATE SUPERPLASTICIZERS ON THE PROPERTIES OF READY-MIX CONCRETE
The article analyzes the experience of using Portland limestone cement for the production of ready-mixed concretes. It is shown that polycarboxylate superplasticizers (PCE) play a decisive role in providing required technological and construction-technical properties of concrete. The data show that the most effective PCEs for maintaining the workability of the concrete mixture over time and obtaining the required strength class of concrete are РСЕ based on modified acrylic polymers.
