Higher-overall performance concrete (HPC) is a comparatively new time period for concrete that conforms into a list of requirements previously mentioned Individuals of the most common programs, but not limited to toughness.
The variable density is Commonly described in kg per m3, where by typical concrete is 2400 kg/m3. Variable density can be as low as 300 kg/m3,[eighteen] Despite the fact that at this density it might have no structural integrity in the slightest degree and would purpose as a filler or insulation use only. The variable density cuts down energy[eighteen] to raise thermal[18] and acoustical insulation by changing the dense large concrete with air or a light-weight product like clay, cork granules and vermiculite.

An early example at Hoover Dam employed a network of pipes amongst vertical concrete placements to flow into cooling water through the curing procedure in order to avoid harming overheating. Equivalent units remain employed; according to volume of the pour, the concrete combine utilized, and ambient air temperature, the cooling procedure may perhaps very last For a lot of months after the concrete is put. A variety of methods also are utilized to pre-amazing the concrete blend in mass concrete buildings.[126]
Greatest energy and toughness can vary from that of normal concrete, depending on compositional specifics.
Titanium dioxide has been additional to concrete mixtures to cut back smog. A daylight Picture-catalytic in between the titanium in this concrete and the smog cuts down bacteria and Grime from accumulating about the area. It can even be accustomed to stop working nitrogen dioxides established by industrial procedures.[44]
