modern construction materials and techniques pptMuch has been made in recent months about the rising cost of bricks. With the economy taking a turn for the better and housebuilding - supported massively by the government s Help to Buy scheme - looking particularly rosy, demand has risen far quicker than manufacturers capacity to increase supply. Thus the most basic laws of economics conspire to push brick prices to an all-time high.
What s more, housebuilders don t just need bricks - they also need people to lay them. And here again the law ....etc

1. INTRODUCTION
The development and growth of human activities have led to rapid increase in traffic density on roads and highways. As a result, the intensity of traffic noise has gone up to unacceptable levels. The consciousness on noise pollution has become significant in developed nations like USA, Japan, China, UK and Australia. Considering the importance of noise abatement, highway noise barriers have been erected at sensitive locations in these countries.

In Indian context, the highways, bu ....etc

INTRODUCTION

Tribology is defined as science and technology of interacting surfaces in relative motion and of related subjects and practices. However the subject Tribology generally deals with the technology of lubrication, friction control and wear prevention of surfaces having relative motion under load.
The two main constituents of Tribology are friction and wear, which controlled and reduced, automatically increases the service life of machine elements.
In past few years, wood iron and skin have been used as journ ....etc

MATURITY TESTING OF CONCRETE

This paper deals with one of the non-destructive testing method known as maturity method, which is used for the determination of concrete strength. This method accounts for the effects of time and temperature on strength development of in-place structures. Some of the new techniques in this approach have also been discussed. Various benefits on using the maturity method in various civil engineering fields are also included in th ....etc

Solar Energy International Biodiesel Workshop



What is a Diesel Engine?

Rudolf Diesel developed the
idea for the diesel engine and
obtained the German patent for
it in 1892.
His goal was to create an
engine with high efficiency.
Gasoline engines had been
invented in 1876 and, especially
at that time, were not very
efficient
Both the gasoline and diesel
engine utilize the process of
internal combustion for power

1. INTRODUCTION
The geotechnical engineers design foundations and other structures on the soil after investigation of the type of soil, its characteristics and its extent. If the soil is good at shallow depth below the ground surface, shallow foundation such as footings and rafts, are generally most economical. However if the soil just below the ground surface is not good but a strong stratum exist at a great depth, deep foundations, such as piles, wells and caissons are required. Deep foundations are quite expensive and a ....etc

Abstract
This study aims to determine the influence of the content of water and cement, water binder ratio, and
the replacement of fly ash and silica fume on the durability of high performance concrete (HPC) by using
artificial neural networks (ANNs). To achieve this, an ANNs model is developed to predict the durability of
high performance concrete which is expressed in terms of chloride ions permeability in accordance with
ASTM C1202-97 or AASHTO T277. The model is developed, trained and tested by using 86 data ....etc

Abstract
Destructive and non-destructive methods have been used for the determination of micro-traces of antimony in high-purity silicon powder. The destructive method was based on sub-stoichiometric radio-activation analysis with solvent extraction using BPHA and cupferron as organic reagents. The antimony contents in high-purity silicon can be determined by the proposed method.
A new non-destructive method was developed for the detection of refrigerant leakage at an evaporator's inflow. Nitrogen and oxygen gas were suc ....etc
