Developing temperature-controlled mixed concrete with reduced heat of hydration for mass concrete applications is aimed at achieving lower core temperatures, minimizing temperature differentials within concrete structures, and ultimately enhancing durability.
Self-compacting concrete (SCC) is a type of fresh, pre-mixed concrete that possesses the ability to flow under its own weight without the need for external vibration to achieve compaction.
The term "Green Concrete" refers to a concrete that has undergone additional measures in its mix design and placement, ensuring a sustainable structure with an extended lifecycle and a low-maintenance surface, which contributes to energy efficiency, reduces CO2 emissions, and minimizes wastewater impacts.
High-density concrete exhibits a density approximately 50% higher than that of conventional concrete, with the potential to achieve densities up to 5200 kg/m3 by utilizing iron as both the fine and coarse aggregate.
The typical composition of the material involves the combination of Portland cement, supplementary cementitious materials, reactive powders, fine sand, limestone and/or quartz flour, high-range water reducers, and water.
Concrete achieving a compressive strength exceeding 60 MPa within 28 days falls into the category of high-performance concretes, offering versatile technical properties suitable for a wide range of construction applications.
Lightweight concrete falls into three primary categories: lightweight aggregate concrete, foamed concrete, and autoclaved aerated concrete (AAC). It can be manufactured using a diverse selection of lightweight aggregates, including materials like volcanic pumice, clay, and slate, among others.
A unique form of porous concrete, designed for flatwork applications, facilitates the direct passage of water from precipitation and various sources. This design helps minimize runoff from a site and promotes the recharge of groundwater.
