ThE EFFECT OF METAKOLIN, MICROSILICA AND NANOSILICA ON THE MECHANICAL PROPERTIES AND MICROSTRUCTURE OF CEMENT MORTAR
Different mineral admixtures of Indian metakaolin, Iranian silica fume and nanosilica were used to produce high performance mortars. Two different sands types with grain size of 0.015-4mm were mixed with type II Portland cement, polycarboxylate superplasticizer,mineral admixture with 650kg/m3 cement content and water/cement ratio of 0.35. Different amount of cement was replaced by metakaolin or...
متن کاملLaboratory Electrical Resistivity Studies on Cement Stabilized Soil
Electrical resistivity measurement of freshly prepared uncured and cured soil-cement materials is done and the correlations between the factors controlling the performance of soil-cement and electrical resistivity are discussed in this paper. Conventional quality control of soil-cement quite often involves wastage of a lot of material, if it does not meet the strength criteria. In this study, i...
متن کاملMechanical Properties of Low Plasticity Clay Soil Stabilized with Iron Ore Mine Tailing and Portland Cement
Due to economical and environmental issues, utilization of mineral wastes, e.g. iron ore mine tailing (IOMT), as road materials can be recommended as a sustainable alternative. In the present study, mechanical properties, as well as resistance to freezing and thawing cycles (F-T) of low plasticity clay soil stabilized with different percentages of Portland cement (0, 6, 9, 12 and 15%) and diffe...
متن کاملPermeability Characteristics of Compacted and Stabilized Clay with Cement, Peat Ash and Silica Sand
The present paper investigates the influence of stabilization with cement, peat ash, and silica sand on permeability coefficient (kv) of compacted clay, using a novel approach to stabilize the clay with peat ash as a supplementary material of cement in the compacted and stabilized soil. In order to assess the mentioned influence, test specimens of both untreated and stabilized soil have been te...
متن کاملAssessing the Implications of Planting Haloxylon aphyllum on the Vegetation and Soil Properties of Stabilized Sandy Desert (Samad Abad, Sarakhs)
Planting Haloxylon aphyllum under oil mulches has frequently been used for stabilizing mobile sands in Iran for during the last three decades. This study is carried out in stabilized sandy desert of Samad Abad-e-Sarakhs to evaluate the implications of planting Haloxylon aphyllum on the vegetation and soil attributes. Sampling was carried out random-systematically in the representative areas of ...
