Polyurethane (PU) is one of the largest polymer products in the plastic family. Structural and
non-structural applications of PU and its variants have become a common and effective …

The recent need to develop infrastructure, driven by global population growth is forcing
societies to construct on any soil type available within their vicinity including weak soils …

This paper studies the effect of crack repairing process on the behavior of pavement at four
ambient low and medium temperatures ranging from− 20° C to 30° C. Asphalt mixture …

Polyurethane/water glass (PU/WG) grouting materials were prepared in presence of different
proportions of catalyst. The effects of catalyst on the mechanical properties, thermal …

This paper aims to investigate drying shrinkage, strength and microstructure of alkali-
activated high-calcium fly ash (AAHF) paste by using FGD-gypsum (FGD) and dolomite …

In this work, a novel waterproof, fast setting geopolymer repair material with hydrophobic
surface and high compressive strength and bonding strength was proposed. The …

Epoxy based grouting materials should concern with low viscosity, high strength, rapid
curing, and low shrinkage. A polyurethane/epoxy grouting material was prepared. Through …

In order to effectively seal the cracks, a novel hybrid toughened unsaturated polyester resin
(RMUP) crack repair material using liquid nitrile rubber (LNR) and nano-montmorillonite …

Pavement, as an important transportation infrastructure, plays an essential role in modern
society. Joints and cracks, which are either designed for or created by internal and external …

In this study, silane coupling agent 3-chloropropyltrimethoxysilane (CTS) was used for
improving the distribution of water glass (WG) in the polyurethane (PU) matrix and …
