Repair of Post Concreting Defects in Structures and Methods of Repair
Post concreting defects in structures are seen after the removal of formwork. Repair of these post-concreting defects and methods of repairs are discussed.
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 ...
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 ...
