CONDITIONS REQUIRED FOR SUBSURFACE MOISTURE PROTECTION

Author: Donald Baerman In some cases, the subsurface spaces of a building are not critical; valuable goods are not stored there, and the spaces are not used for critical operations. In these instances, occasional leaking may be tolerated, and neither dampproofing nor waterproofing may be needed. Dampproofing is generally adequate to retard passage of water into a basement, and subsurface drainage is provided by natural ground absorption and/or evaporation, under...

HOW TO DETERMINE WHERE TENSILE AND COMPRESSIVE STRESSES OCCUR IN STRUCTURAL MEMBERS OF A BEAM 1

HOW TO DETERMINE WHERE TENSILE AND COMPRESSIVE STRESSES OCCUR IN STRUCTURAL MEMBERS OF A BEAM

It is convenient to consider the behaviour of an elastic material. For instance, the diagram above illustrates Indian Rubber under stress. A bar of rubber laid across and not fixed to two supports bends under load and the top surface shortens and becomes compressed under stress and the bottom surface stretched under tensile stress. A member that is supported so that the support do not restrain bending under load is...

AGGREGATE IN CONSTRUCTION, TYPES AND CHARACTERISTICS 4

AGGREGATE IN CONSTRUCTION, TYPES AND CHARACTERISTICS

Aggregates are particles of broken stone and sand which form the major component parts of concrete. Aggregate materials commonly used for concrete are sand and gravel. In construction, the material which binds the aggregates together is cement and it is described as matrix. Characteristics of Aggregate Aggregate for concrete should be hard and durable. It should not contain materials like clay, coal or pyrites that decompose or change in volume...

Building Components

The approach we take to design and erect our building depends on some number of fundamental principles. The building has to resist force of Gravity, hence remains safe through its design life. Every building is composed of some common elements, namely: Foundation Floors Roof Walls Doors and Windows Stairs and Rams Beams Hence, Building Components are the various parts that makes up a complete building.
