全球预测混凝土市场报告(2017-2021年)
Ready-mix concrete is manufactured in a factory or a plant, within certain specific
guidelines, such as in the ratio of 3:2:1, i.e., 3 parts aggregates, 2 parts water, and 1
part cement, and then delivered to a construction site through a truck equipped with
transit mixers.
When aggregates are mixed together with dry Portland cement and water, the mixture
forms a thick fluid mass that easily molds to a predefined shape. The cement reacts
chemically with water and other ingredients to form a hard component that binds the
materials together into a durable, harder material that has many uses.

拉丁美洲水泥手册(消费仍是一个挑战)
Cement consumption in 2017 should grow in the mid- to high single digits, recovering some of the lost ground of 2016. The reactivation of public investment should be positive for cement demand. The gradual recovery of macroeconomic stability, including expectations of falling inflation, reduced interest rate volatility and more predictable fiscal policy, should be supportive of private investment and could lead to a renaissance of cement demand growth.

北美MEP服务市场报告(2017-2021年)
Mechanical, engineering, and plumbing (MEP) services hold critical importance in
ensuring that building facilities are operating in an efficient manner with the optimum
use of energy. To achieve better results, building owners are increasingly entering
long-term contracts with third party specialized vendors. Outsourcing of MEP services
to specialized vendors helps in reducing the operational cost, optimizing the energy
consumption, and improving the productivity of facilities.

全球屋顶粘合剂市场报告(2017-2021年)
The building and construction industry is witnessing substantial investment not only in
emerging economies such as India and China but also in developed countries such as
the US. The governments of China, India, Japan, the US, Turkey, France, the UAE,
and Qatar are spending substantially in various infrastructure facilities. In addition, in
countries such as Saudi Arabia, the UAE, and Qatar, the government's focus has
shifted toward the non-oil sector, owing to which the investment contribution toward
construction activities has increased substantially over the years.

全球隧道和凿岩设备市场报告(2017-2021年)
The tunnel boring and rock drilling machines are used to excavate holes for tunnels
through different kinds of soil and difficult rocky terrains as an alternative to
conventional blasting methods. Machines operate effectively by reducing the
disturbance to the ground while boring through any difficult terrain. Typically, a tunnel
boring and rock drilling machine comprise a rotating cutting wheel, followed by the
main bearing, trailing support mechanisms, and a thrust system. Based on the
geographic terrain of the region, different types of tunnel boring and rock drilling
machine are used. As the machine functions smoothly, it is majorly used in highly
urbanized areas to complete drilling work in less time. However, the upfront cost
involved to assemble the equipment and difficulties experienced while transporting
them across different sites is one of the main drawbacks of the tunnel boring machine
(TBM).
