The high performance concrete is a highly complex material that consists of cement, water, blast furnace slag, super-plasticizer, coarse and fine aggregate. All of the materials play a certain role in the compressive strength of concrete. Combined with the information about age, the compressive strength of concrete is determined by eight attributes: 1. Cement (kg/m!) 2. Fly ash (kg/m!) 3. Blast...
The effects of soil intrinsic properties on soil structural stability were evaluated. Soil samples (33 series) with wide ranges of properties and structural stability were collected from Hamadan province. Two structural stability indices were used: mean weight diameter (MWD) using Yoder method and De Leenheer-De Boodt index (DDI). Wetting pre-treatments (fast wetting to saturation and slow wett...
Abstract Concrete is the second most used material on earth after water. The current era of concrete making like coarse and fine aggregate need alternatives to overcome demand. In this present study, artificial or sand (AS) as an alternative has been investigated. parameters studied in study investigate AS effect are slump, modulus rapture, compression strength, split-tensile shear strength. ex...
There is an increasing requirement for the production of concrete globally, due to rapid infrastructure development, leading to shortage in the availability of raw materials, which in turn increase its costs. At the same time, many waste materials are also produced as by-products from various industries and construction sites, the disposal of which cause a major problem. Thus it becomes necessa...
today, persian poetry is of great importance to many scholars around the world. the interest and attention of various cultures toward such a fine literature has given quite a good motivation for a comparative study. the major concern of the study is to investigate how nature is depicted through the works of the great english poet, william wordsworth (1770-1850) and the outstanding contemporary ...
