Challenges Facing the Concrete Industry

Concrete being the premier building material is used in vast quantities. There are no reliable statistics on world concrete production, but there are statistics on world cement production. In 2016 about 4.6 billion metric tons of cement were produced [1] with China producing half of this cement, Figure 1 [1]. As cement has several uses, converting this figure to cubic metres of concrete

Concrete Production - an overview ScienceDirect Topics

Concrete production is a highly intensive energy-consuming process and presently facing a number of challenges in reducing the carbon footprint and making it more economic. Sustainable technologies in maintaining concrete structures are proving to be a great challenge. Microbially induced carbonate precipitation (MICP) has developed as a novel and sustainable technique in improving the ...

Types and Causes of Concrete Deterioration

leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan- sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2). Steel corrodes because it is not a naturally occurring material. Rather, iron ore is smelted and refined to produce steel. The ...

Concrete Slab Surface Defects: Causes, Prevention, Repair

The appearance of blisters (Fig. 1) on the surface of a concrete slab during finishing operations is annoying. These bumps, of varying size, appear at a time when bubbles of entrapped air or water rising through the plastic concrete get trapped under an already sealed, airtight surface. Experienced concrete finishers attribute blistering to three principal causes: 1. An excess amount of ...

7 Types of Construction Defects in Reinforced Concrete ...

Errors during reinforcement installation could lead to serious concrete deterioration. For instance, inadequate chair bars and insufficient tying of reinforcement would cause rebar movement which may lead to inadequate concrete cover and reduction in effect depth of the concrete section. As a result, the durability of the concrete structure is compromised and the structure would be vulnerable ...

Cement and Concrete: Environmental Considerations ...

01/03/1993  Energy use for concrete production looks considerably better than it does for cement. That’s because the other components of concrete—sand, crushed stone, and water—are much less energy intensive. Including energy for hauling, sand and crushed stone have embodied energy values of about 40,000 and 100,000 Btus per ton, respectively. The cement, representing about 12% of concrete

Environmental impact of concrete - Wikipedia

The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.
