Standard ready-mix concrete is the most common form of concrete. It is prepared for delivery at a concrete plant instead of mixed on the construction site, which guarantees the quality of the concrete. This type of concrete can provide a structural function, as well as an aesthetic or decorative finish.
hardened cement paste. Di erent concrete types with special cements have been prepared. The linear attenuation coe cients of conventional concrete and concrete with supplementary mineral additives (barite and witherite) at di erent gamma energies (Co-60: 1.25 MeV, Cs-137: 0.662 MeV, Ir-192: 0.37 MeV) in narrow beam conditions have been measured.
Jan 25, 2021· The partial replacement of cement with a self-healing additive, in the long term, can also benefit the global efforts for CO 2 emission reduction (Ghosh and Mandal 2018; UN 2015). There are also numerous causes of cracking in concrete, and the initial laboratory results indicated the ability of this system to deal with controlled stress-induced ...
It is common to use cement additives that increase the mechanical strength by chemical activation, without changing the cement surface and particle size distribution. Alkanolamines are frequently used and are able to increase the compressive strength (at different or all age) by max. five MPa. Typical examples are SikaGrind®-200 and SikaGrind ...
