However, using recycled concrete aggregate (RCA) in concrete involves various obstacles and
controversial issues in controlling the quality of recycled concrete aggregate (RCA). Recycled concrete aggregates is the base of mechanical and testing of concrete under various conditions. In this time natural aggregates is more consumption and reduce it. Then Recycled concrete aggregates where natural aggregates are replaced with RCA is a technology for conserving natural resources and also the reducing the environmental impact of concrete. In cement test include consistency test, initial setting time test, and final setting time test. Aggregate test is also included impact valve test,abrasion test and sieve test and water abrasion test. Tests were undertaken to establish the compressive strength,workability and water absorption of each batch. The results indicate that the compressive strength is not the only decisive factor on mechanical and durability-relatedproperties of RACs.

High cost is dominating factor of conventional construction material which affecting in the housing
system as an alternative method to overcome this drawback. Natural fibres, coir fibre has maximum amount of lignin giving maximum strength as well as are durable in nature. This paper presents an experimental study of coir fibre concrete and its strength comparison with plain cement concrete. Reinforcement of concrete is necessary to enhance its engineering properties. For this study, coconut fibres were used as they are freely available in large quantities. It is necessary to make research any alternative material. The study comprises of comparative statement of properties of coconut fibre reinforced concrete with conventional concrete based on experiments performed in the
laboratory. The coir fiber concrete decreases the cost and increase the strength of concrete. In the study found the optimum fibre content to be 1% ,3%,5% by weight of cement) The addition of coconut fibres improved the compressive strength of concrete by about approximately 13% they also formed good bonding in the concrete. Further work is required by changing the fibre content and aspect ratio to determine the optimum range of fibre content so that fibre reinforced concrete can be used where high compressive required.

STUDY, PREVENTION AND REPAIR OF CRACKS IN BUILDING Journal Article
In: International Journal of Engineering, Management & Technology (IJEMT), vol. 1, iss. 06, pp. 17-23, 2022, ISSN: 2583 - 4517.
Generally, there is no building construction with zero cracks. It’s a very common and unavoidable problem in any concrete construction structure. Cracks affect structural safety as well as the beautiful and artistic appearance of any construction. Everyone wishes their construction or building to be crack free, but it is not an easy task or almost impossible. Various types of cracks start to appear on the nonstructural and structural part of any construction. These cracks are the result of some unwanted or faulty steps taken during construction. Sometimes, cracks can be a serious concern about the safety of any construction.
Cracks do not risk the safety directly, but they encourage some acts which cause major safety problems.
Therefore, it is very important to detect cracks before they create any serious safety issue and take preventive measures. However, cracks cannot be completely prevented, but can be controlled by using adequate materials and techniques. The present paper analyses reasons of cracks formation and provides some techniques and measures that can prevent cracks and related issues.

THE BASIC CONCEPT OF CYBER CRIME Journal Article
In: International Journal of Engineering, Management & Technology (IJEMT), vol. 1, iss. 06, pp. 24-44, 2022, ISSN: 2583 - 4517.
Cyber Crime is a common phenomenon in the world. Cyber Crime is that group of activities made
by the people by creating disturbance in network, stealing others important and private data, documents, hack bank details and accounts and transferring money to their own. Cyber Crime, especially through the Internet, has grown in importance as the computer has become central to commerce, entertainment, and government. Cyber crime, also called computer crime, the use of a computer as an instrument to further illegal ends, such as committing fraud, Trafficking in child pornography and intellectual property, stealing identities, or violating privacy. The cyber crime and they its impacts over the society in the form of economical disrupt, psychological disorder, threat toNational defense etc. Restriction of cyber crimes is dependent on proper analysis of their behavior and understanding of their impacts over various levels of society. Now a day’s Cyber crime is increasing day by day. People have been greatly suffering for it. It is not only creating human suffering but also put effect on it. So Cyber Crime is one of the major crimes done by computer expert. This paper gives the basic concept of cyber crime.

Earthquake is a natural phenomenon occurring with all uncertainties.It. It is Very serious
problem since they affect human life in various ways. Now a days to prevent the buildings there are several techniques and methods to resist earthquake effects such as ; Base isolation, seismic Dampers, steel plate shear walls ,Hollow foundation. These ground motions cause structures to vibrate and induce inertia forces in the structural elements. In the absence of seismic design, the building may fail,leading to a catastrophe. The seismic design philosophy aims to primarily ensure life safety and secures the functionality of the building. In conjunction with the design philosophy, it is essential to adopt earthquake-safe construction practices for the efficient seismic performance of a building. This paper is a review on various researches carried out by various researchers and engineers on such systems.
