| Summary: | "Preface The construction industry is very conservative.
This can be seen as deriving from the special nature of
its work which is creating the social and economic
infrastructures required by each particular age in a
"safe" way. Architecture is to some extent ahead of its
time in the design of buildings but also reflects the
inclinations of clients. In other words, the basic
activity of the construction industry has been to reliably
translate social needs into material form. Naturally, with
the growing sophistication of requirements, construction
technology has developed and many breakthroughs have been
achieved to make the impossible possible, but this process
has also been marked by many failures. The construction
industry can be said to have built its technology systems
through a process of "experience engineering." The
construction industry exhibits a high degree of locality.
Structures have generally been built by local people using
local materials. Globalization has promoted
internationalization in the construction industry as
elsewhere, but the basics of construction systems have
remained unchanged. What makes this possible is the wide
use of concrete as a construction material. Its primary
component materials are aggregate, cement, and water, with
aggregate constituting approximately 70% of the total
volume. The Earth's crust is composed of rocks that are
the raw materials for aggregate. Water, when seawater is
included, is the most commonly available globally
circulating substance on Earth. In the case of cement, the
raw materials are limestone and clay, both of which are
also available in abundance"--Provided by publisher |
