铸造混凝土

W.hat Does Cast-In-Place Concrete Mean?

铸造混凝土是一种施工技术，其利用临时模板来塑造混凝土浆料，直至其硬化。它有许多应用，包括住房施工，排水沟，传统开放式管道施工，以及制造天桥建筑行业的混凝土管道。

制热混凝土安装的较新方法包括使用使用离心力的机器将混凝土吹到现有金属管的墙壁上。

Cast-in-place concrete is also known as poured-in-place concrete.

T.renchlesspedia Explains Cast-In-Place Concrete

使用一个预先设计模筑混凝土formwork into which the cement slurry is poured. The concrete may be reinforced to add additional strength and prolong the life of the structure or product. Once the concrete hardens, the formwork is removed and the structure or product is allowed to be cured before use.

一个简短的历史

T.homas Edison championed the use of removable forms in the construction of concrete houses。T.he technique was predominately used for the casting of basement walls using low-grade material, but Edison built several prototypes that remain standing today.

铸造混凝土管（CIPCP）已在许多不同的设置中使用，包括单片混凝土灌溉管道。1994年关于这个主题的论文的作者，Charles M. Burt和John M. Wegener解释了CIPCP在加利福尼亚州土耳其灌区的1922年。它被认为是其他形式的管道的低成本替代品。

Concrete Formwork

用于铸造混凝土的模板限定了结构或产品的最终形状。胶合板和碾磨的木材是commonly used formwork materialwhich can be made from waste material. The formwork can be dismantled easily and reused many times, making it an economical option.

T.o prevent the concrete from bonding to the formwork, form-releasers, or parting agents such as diesel fuel and motor oil was traditionally used. Since they are volatile organic compounds (VOCs), they are prohibited for use by state and federal regulations such as the Clean Air Act.

一世t is recommended to use form-release compounds that are made using biologically derived oils which will help reduce the impact on the environment and the construction crew. They are also less expensive than traditional form-release compounds.

B.enefits of Cast-in-place Concrete

• 它具有高强度

• Can be applied for foundation and basement work

• 抵抗结构损伤

• 结构或产品可以加强使其更强壮

• 提供高度的绝缘度

• 提供隔音

• P.revents mold, mildew, and dampness to a large extent

这些性质主要是由于铸造的混凝土不含预制混凝土部分之间的关​​节中存在的自然裂缝或间隙。
