Sulfate Amage To Concrete Floors On Sulfate Bearing Hardcore

Offers guidance on the damage to houses and other dwellings caused by sulphate attack to floor slabs resulting from use of sulphate-bearing hardcore. This document highlights several options for procedures for investigation, assessment and remedial measures. This document, prepared by the Building Research Establishment (BRE), provides authoritative guidance on the damage to houses and other dwellings caused by sulphate attack to floor slabs resulting from past use of sulphate-bearing hardcore. Written for local authorities, professionals and homeowners, this document highlights several options for procedures for investigation, assessment and remedial measures.

Sulfate Attack on Concrete provides a comprehensive reference to this important subject. It covers: a short history of concrete deterioration due to sulfate attack, the origin of sulfates in concrete, the importance of appropriate concrete processing, forms and physical-chemical mechanisms of concrete deterioration due to sulfates, preventative mea

This is the first book to offer a systematic and analytical overview of the legal framework for residential construction. In doing so, the book addresses two fundamental questions: Prevention: What assurances can the law give buyers (and later owners and occupiers) of homes that construction work – from building of a complete home to adding an extension or replacing a shower unit – will comply with minimum standards of design, safety and build quality? Cure: What forms of redress - from whom, and by what route - can residents expect, when, often long after completion of construction, they discover defects? The resulting problems pose some big and difficult questions of principle and policy about standards, rights and remedies, which in turn concern justice more generally. This book addresses these key issues in a comparative context across the United Kingdom, Ireland, Australia and New Zealand. It is an accessible guide to the existing law for residents and construction professionals (and their legal advisers), but also charts a course to further, meaningful reforms of the legal landscape for residential construction around the world. The book's two co-authors, Philip Britton and Matthew Bell, have taught in the field in the UK, Australia and New Zealand; both have been active in legal practice, as have the book's two specialist contributors, Deirdre Ní Fhloinn and Kim Vernau.

This study therefore investigated and improved cementitious properties of pozzolan blended with calcium hydroxide, gypsum and cement in order to extend its use from low strength mortars to concrete works which can be used for low to medium rise structural applications. Characterization, strength tests and durability tests were performed on pozzolan mixtures under laboratory conditions and the effects of adding gypsum to pozzolan and calcium hydroxide mixtures on the compressive strength and durability of cured concrete specimens were investigated.

The 18 papers grapple with new problems and old ones that remain unresolved concerning sulfate attack on concrete, not considered one of the most prevalent mechanisms of concrete deterioration, but one that has received much attention lately because of costly litigation against manufacturers, developers, and others. The topics include the role of ettringite in external sulfate attack, microstructural alterations in permeable concrete, assessing damage and predicting service life of venerable concrete, a marine environment, and the adequacy of standards.
