自从二十世纪三十年代配料厂提供搅拌车载预拌混凝土以来，RMC就一直被认为是英国混凝土市场的领导者。而RMC在2005年被Cemex收购。
但企业发展服务市场研究表示，在其年度行业调查中，它已经确认Tarmac是英国头号混凝土供应商。虽然Cemex仍在经营英国的大多数厂。
该调查估计的Tarmac所占有的市场份额刚刚超过20%，而Cemex刚好在此数额以下。Hanson紧随其后排在第三。
企业发展服务机构共计确认了250个仍然提供搅拌车运送混凝土的公司。此外，还有150家公司供应体积货车运送的混凝土。它表示，从2008年4月市场开始下降，并将持续整个2009年。但是，预期2010年市场在一个低起点上将有一些缓慢的增长。

Tarmac becomes concrete market leader
(UK) -- Tarmac has become the largest concrete company in the UK, ahead of Cemex, according to new research.
RMC, which became Cemex in 2005, is thought to have been the market leader since truck-mixed concrete was supplied from batching plants in the 1930s.
But BDS Marketing Research said that it had identified Tarmac as the number-one concrete supplier in its annual survey of the industry, although Cemex continues to operate the most plants in the country.
The consultancy puts the estimated market share of Tarmac at just over 20%, with Cemex just under this threshold. Hanson is close behind in third place.
BDS has identified a total of around 250 companies that continue to supply concrete truck mixed concrete. In addition, there are another 150 companies which supply concrete in volumetric lorries.
It said that the market started to decline in April 2008 and will continue to do so throughout 2009. However some slow growth from a low base is expected in 2010.
