Chemical and mineralogical alterations of concrete subjected to chemical attacks in complex underground tunnel environments during 20–36 years
TL;DR: In this paper, the chemical and mineralogical alterations of concrete in underground tunnel structures built from 1980 to 1996, located on the China's east seashore were investigated, and it was found that C50 pre-cast concrete shows a higher resistance compared with C30 cast-in-place concrete, mainly due to the low water to binder ratio.

Rheology and mechanical characteristics of self-compacting concrete mixtures containing metakaolin
TL;DR: In this paper, the effect of replacement of cement or limestone powder by metakaolin, on the rheology and the mechanical characteristics of the concrete mixtures was investigated, and it has been found that rheological behavior of SCC is affected by the incorporation of metakaol.
Journal ArticleDOI
Microstructural studies on eco-friendly and durable Self-compacting concrete blended with metakaolin
TL;DR: In this paper, a self-compacting concrete (SCC) was prepared with metakaolin (MK) as a partial replacement of ordinary Portland cement (OPC) and the positive environmental effect of MK has studied by calculating the CO 2 emission during the OPC and MK production.

Mechanism of sulfate attack on portland cement concrete — Another look
TL;DR: The chemical phenomenon of ettringite formation as a result of reaction between sulfate water and hydration products of portland cement does not adequately explain all the physical manifestations of the sulfate attack as discussed by the authors.
