Brick Work – Types, Bonds,Tests

INTRODUCTION

Construction evidences with brickwork from many parts of the world reflects the existence of brickwork even from prehistoric time and the

Delays On Construction Industry

Construction industry is an important element in the evolution of economy of a nation. Delays on construction projects are very common and listed as international catastrophe. Construction delays are defined as failure to keep up the project with planned contract schedule. Number of reasons exists to point out the reasons for delay in the field of construction. Proper identification of delay will mitigate the effects caused by those construction delays. This study research is to identify the major causes of delays, effects on construction project by those delays and finding the remedies to minimize those delays.

From the past researches and projects it is noted that the delays of construction projects are categorized into number of types such as critical or non critical, excusable or non excusable, concurrent or non concurrent and compensable or non compensable.

MECHANICAL COUPLERS

The general practice, in case, the length of the stocked rebars is not enough for the full length of the elements, lapping is required to join the bar lengths’ together. Provision of required lap length to the bars is necessary which is ensuring the maximum transmission of the load stresses from one bar to another.

THE PROBLEM WITH LAPPING BARS:

In the highly loaded structures, and/ or the section size to be kept being smaller for architectural purposes, the reinforcement will be congested in that section. So, lapping the bar at this state, will generate more unwanted stresses to the element at the lapping locations.

So mechanical couplers are used to join the rebars eliminating the extra bar size added to the section and also which is reducing the effectiveness of the section.
