内容説明・目次
内容説明
Construction Science & Materials is designed to cover topics studied at levels 2 - 5 on Construction HND courses and is also suitable for first year undergraduates on construction courses as well as Building surveying, Architectural Technology and Quantity Surveying. It is an essential text for those who have done no science since their GCSEs.
Divided into 17 chapters, each with written explanations supplemented by solved examples and relevant diagrams to substantiate the text. Chapters end with numerical questions covering a range of problems and their answers are given at the end of the book and on the book's website.
