Mid-range water-reducing admixtures were developed to increase the slump beyond the range available with regular water reducers without the excessive retardation that had been known to occur. trailer 0000012509 00000 n Retarding admixtures, which slow the setting rate of concrete, are used to counteract the accelerating effect of hot weather on concrete setting. Are required to achieve a minimum 5% water reduction. This application is ideal for use with lean, harsh ready mix concrete mixes or concrete containing fly ash. The product may be used in a wide variety of applications, including ready mix, job site, and concrete paving plants for normal and lightweight concrete, and precast products. Ideal for lean, harsh, ready-mix concrete. Mid-range water reducers can decrease the amount of water used by 15%, and can also help keep the setting time for the concrete more stable, giving more control over how quickly or slowly the concrete dries. improved finishing when compared to a normal water reducer. High temperatures often cause an increased rate of hardening which makes placing and finishing difficult. Its adjustable slump and surface slickness minimize time delays on projects where placement is difficult or pumping is necessary. 0000013933 00000 n Water Reducers, High-Range High levels of water reduction for outstanding engineering performance The technology and versatility of the superplasticizers portfolio excels in high performance areas such as high strength concrete, pumpability, self-consolidating concrete, low permeability, low water absorption concrete and low shrinkage applications.
