Abstract:
Concrete plays a vital part in construction industry. However, the production of concrete, notably cement, pose sustainability issues that need to be managed. To improve the sustainability of concrete, innovative admixtures, which contain Calcium Silicate Hydrate (C-S-H) nanoparticles, were developed at Master Builders Solutions. The patented admixtures can significantly enhance concrete strength at early and late ages. The use of this concrete admixtures enhances a reduction of considerable amounts of cementitious materials, typically in range from 50 lb/yd3 (30 kg/m3) to 100 lb/yd3 (60 kg/m3) to achieve similar strengths of those control concrete mixtures without the admixtures. In other hand, these innovative admixtures also enable a higher replacement of portland cement with supplementary materials such as fly ash, slag cement and milled limestone, reduction of heat-curing and/or curing time. The information presented will show how the use of the nanoparticle-based admixtures can provide options to modify, improve properties, increase the speeds of concrete curing and construction process, and reduce CO2-footprint of the concrete mixtures.
