Title of the articleInfluence of plasticizers on physical and mechanical properties of soil-cement for road purpose
Abstract.Today one of the popular tasks for Russian Federation road-transport complex is the development of the road network, including the connection of rural settlements with public roads. The replacing of imported crushed stone in the construction of highways by soil-cement regional network is one of the advanced areas of intensification and reducing of road construction’s costs. When clay varieties of soils are strengthened by Portland cement, sometimes it is necessary to increase the strength and frost resistance by using surfactant additives of hydrophobic and hydrophilic types. Hydrophobic additives have been studied previously and showed high efficiency with improved properties soil-cement. Hydrophilic plasticizers are widespread in the production of concrete and reinforced concrete, but their application in soil-cement is poorly known. Therefore the aim of this work was to study the influence of hyper- and superplasticizers on the physico-mechanical properties soil-cement road purpose. The positive influence of plasticizers on mechanical properties soil-cement was estimated. The maximum effect is achieved when polycarboxylate hyperplasticizer Odolit-K was applied. The obtained results were received due to more effective repulsion cement flocculation, which allows water move nearer to cement clinker particles. This feature of plasticizers is allows to get soil-cement M40 and M60 without increasing the amount of binder. Required resistance to frost F15 is not obtained in any of the studied compounds, however, it is possible to achieve using complex administered hydrophobic silicone compounds.
