TL;DR: In this paper, the potential benefits of steam-cured concrete, particularly on mixes incorporating mineral admixtures, were explored, and it was found that steamcured concretes were more porous as indicated by the much higher sorptivity values compared with standard-Cured specimens.

TL;DR: In this article, a set of monoliths that set rapidly and harden at ambient temperature have been prepared by exploiting sol-gel type condensation reactions between sodium silicate, formed in-situ by alkaline dissolution of silica fume and a solution of sodium aluminate.
Abstract: Monoliths that set rapidly and harden at ambient temperature have been prepared by exploiting sol–gel type condensation reactions between sodium silicate, formed in-situ by alkaline dissolution of silica fume, and a solution of sodium aluminate. Structural characterisation of the product was carried out by XRD, 27Al and 29Si MAS NMR spectroscopy) and the samples showed reproducibly good compressive strengths, indicating that the products display all the characteristics of typical aluminosilicate geopolymers.

TL;DR: In this article, the results of the examinations of abrasive wear of the nine types of high-strength concrete (HSC) with compressive strength of 75÷120 MPa were presented.

TL;DR: In this article, the effects of the addition of silica powder, silica fume, fly ash, and hemihydrated gypsum to the interface of new-to-old paste on the enhancement of bond strength were investigated.

TL;DR: In this paper, five surface treatment methods (cement coating, silica fume coating, sodium hydroxide, potassium permanganate and sulphuric acid soaking) were used to mitigate strength loss in concrete composite foam with RTC.
