Effect of different superplasticisers on the physical and mechanical properties of cement grouts
TL;DR: In this paper, the effects of polycarboxylate superplasticiser (PCE) on the rheological properties, mechanical strength, final setting time and bleeding of cement grouts in comparison to that of a polynaphthalene super-agent (SNF) were investigated.
Journal ArticleDOI
Experimental study on performance of cement-based grouts admixed with fly ash, bentonite, superplasticizer and water glass
TL;DR: In this paper, the ASTM Type I Portland cement (PC), class F fly ash (FA), bentonite (B), superplasticizer (SP) and water glass were designed to improve properties of grouting materials in different aspects.
Journal ArticleDOI
Improving the strength of weak soil using polyurethane grouts: A review
TL;DR: In this paper, a literature review and collecting information on the application of polyurethane chemical grout for improving the properties of weak soils has been conducted and the review concluded that improved polyurethsane has the potential to improve weak soil types for infrastructure development.
Journal ArticleDOI
Combined effect of superplasticizer, silica fume and temperature in the performance of natural hydraulic lime grouts
TL;DR: In this paper, the effect of environmental temperature over superplasticized hydraulic lime-based grouts with partial replacement of lime by silica fume was analyzed in fresh and hardened state by testing its rheological behaviour, injectability and hydration reactions kinetics.
Journal ArticleDOI
Fundamental properties of epoxy resin-modified cement grouts
TL;DR: The use of additives to improve the quality of cement grouts and their effects on strength, durability and resistance to chemical erosion of grouted soil or rock mass is crucial for geotechnical engineering, especially in foundation construction as mentioned in this paper.

Concrete : structure, properties, and materials
TL;DR: In this article, the authors introduce concrete strength, dimensional stability durability, and early-age properties of hardened concrete, including hydraulic cements aggregates admixtures proportioning normal-weight concrete mixtures.
Journal ArticleDOI
Engineering properties of medium-to-fine sands injected with microfine cement grout
TL;DR: In this paper, the authors investigated the penetrability of microfine cement suspensions prepared with Rheocem 900 with and without superplasticizer additive into various graded fine-to-medium sands into which chemical grout permeation is only possible.
Journal Article
Study on the contribution of the fineness on cement strength
TL;DR: In this paper, the most important parameters influencing the strength of cement are the uniformity factor and the content of particle size fraction 3-32 {mu}m. This fact is due to the introduction of high efficient separators in final grinding of cement and the attempt to exploit their advantages at the maximum.
Journal Article
Innovative materials and methods for ground support, consolidation and water sealing for the mining industry
TL;DR: In this article, the advantages of a cementitious TSL in temporary support as well as the full range of injection materials available for any ground or water problem are discussed, and the flaws in present cementitious grouting procedures and new concepts for water control to owners and contractors.
