The aim of the Project is to find out the shear strength parameters of fly ash and fly ash mixed soil, which can act as a stabilizer to many soils in geo- engineering field. The project describes the use of local fly ash in construction industry in a way to minimize the industrial waste. Their been serious shortage of natural material, which are used in Highway or Earth dam construction. Due to soil excavation, deforestation occurs which affects the bio-diversity. Industrial waste such as fly-ash, slag etc can be effectively used in soil stabilization. Several geo engineering Laboratory...

In this thesis, a methodology has been proposed for strengthening of existing buildings for additional base shear demand and serviceability requirement using visco elastic dampers. Seismic zone map in Indian standard IS 1893 Part 1 2002 is being revised from time to time which leads to increase in elastic demands on existing buildings. Base shears for a typical low rise (three storey) and high rise (twenty storey) buildings for zone 2, zone 3, zone 4 and zone 5 for hard soil condition are estimated using seismic coefficient method and time history analysis with spectrum compatible...

Concrete is one of the most produced materials in the world. The amount of cement, the binder in concrete, produced in 2017 total of an astounding 4.1 billion tonnes. However, traditional concrete has inherent weaknesses, and despite the durability of concrete, cracking is inevitable. Cracks develop in concrete when it is exposed to conditions such as excessive stress, temperature fluctuation, and corrosive chemicals. Selfhealing concrete is a promising new technology that will change the way structures are maintained. When concrete cracks, the crack allows water and carbon dioxide into the...

Now-a-days the population is increasing day by day so the necessity of the houses is also increasing. The consumption of cement is very high.so there is a chance to decrease the usage of cement by replacing it with fly ash up to certain proportions. This investigation is to study the effects of replacement of cement (by weight) with four percentage of fly ash and the effects of addition of steel strip pieces in partial replacement of coarse aggregate. A control mixture of proportions 1:1.5:3 with w/c of 0.45 was designed. Cement was replaced with three percentages (15%, 30%&45%) of Class F...

This study presents a comparative study between Artificial Neural Network (ANN) and Response Surface Methodology (RSM) in predicting the compressive strength of high strength concrete. The comparison was made based on the same experimental datasets. The inputs investigated in this study were percentage of Cement, Silica fume and coarse aggregate. The methods employed in ANN and RSM were feedforward neural network and face-centered central composite, correspondingly. The comparison between the two models showed that RSM performed better than ANN with coefficient of determination (R2) closer to...
