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 ....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 ....etc

Introduction
The properties of concrete depend on the quantities and qualities of its components. Because cement is the most active component of concrete and usually has the greatest unit cost, its selection and proper use are important in obtaining most economically the balance of properties desired for any particular concrete mixture.
History of the origin of cement
It is uncertain where it was first discovered t ....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 dat ....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

Supplementary Cementitious Materials
Types of SCMs
• Natural (ASTM C 618 Class N)
• Produced from natural mineral deposits (e.g., volcanic ash)
• May require heat treatment (e.g., metakaolin)
• Processed / Manufactured
• Silica fume (ASTM C 1240)
• Slag (ASTM C 989)
• Fly Ash (ASTM C 215)
Benefits of SCMs
• Industrial by-products (waste utilization)
• Typically cheaper than cement (except for silica fume and metakaolin)
• E ....etc

ABSTRACT
Soil stabilization can be done in many ways. But the stabilization using waste plastic fibers is an economic method since the stabilizer used here is waste plastic materials, which are easily available. This report presents the various tests conducted on fiber reinforced soil with varying fiber content and their results are analyzed such that weather it can be used in the field.
Literature reviews discuss tests like CBR test, shear strength test, consolidation test, swelling test, shrinkage limit, desiccation cracks and hydr ....etc
