Introduction This document provides an overview of consequence classification for dams in British Columbia. It outlines a rough method for assessing consequence and some key concepts that require consideration in assessing consequence. If the method provides a clearly defined consequence classification then a consequence classification can be assigned. If the results are uncertain, use of the higher possible consequence classification is appropriate or a more detailed assessment method should be used. For larger structures or complicated downstream channel conditions more detailed procedures may be required These guidelines are only intended for consequence of failure classification. They are not adequate for the preparation of inundation mapping for Emergency Preparedness Planning (EPP), or for the assessment of hazards and risk analysis.

Concrete Concrete is an intimate mixture of: Cement, Sand (Fine Aggregate), Coarse Aggregate, Water. New Generation Concrete needs use of Special Materials in addition to above i.e. “ADMIXTURES” Admixtures may be Mineral or Chemical Admixtures Versatility of making concrete with locally available materials, ease in molding it into any shape and size and economy in its making has made concrete the 2nd largest consumed material on earth!! Requirements of Good Concrete A good concrete should: meet   the strength requirements as measured by compressive strength, fulfill durability requirements to resist the environment in which the structure is expected to serve, be mixed, transported and compacted as efficiently as possible and will be as economical as possible Concrete Durability “Durability of concrete is the ability of concrete to withstand the harmful effects of environment to which it will be subjected to, during its service life, without u
