Concrete Formwork Design Considerations – Basis for Concrete Formwork Design
Design and building concrete formwork effectively requires a basic understanding of how concrete behaves as it exerts pressure on formwork. Concrete exerts lateral pressure on the formwork. The formwork is designed based on these lateral forces. Concrete Formwork Design Considerations ...
Different Failure Modes of Concrete Columns – Compression Members
There are three modes of failure of concrete columns (compression members) i.e. failure due to pure compression, combined compression and elastic instability. These modes of failures of concrete compression members are discussed.
Types of Construction Project Costs – Direct and Indirect Costs
Any construction project consists of direct and indirect costs which forms the total costs and expenses resulting from the use of principal components for implementing construction projects. Different classification of construction project costs and their features are explained below. Types ...
Tests for Workability of Concrete at Construction Site and Recommended Values
Various tests for workability of concrete at construction sites i.e slump test, Vee-bee test, Compaction factor test and its recommended values are given.
What are Different Tests for Concrete Quality Check?
Quality tests on concrete are performed as a part of quality control of concrete structures. Different quality tests on concrete such as compressive strength tests, slump tests, permeability tests etc.are used to assure the quality of the concrete that is supplied ...
