The temperature-controlling measures of low temperature pit entry cover the followings: appropriate regulation of production time,use of high temperature starter,decrease of grinding degree of raw materials and caky start.

Discussion on temperature control measures of massive concrete;

Concrete temperature control standards,allowable maximum temperature and joint grouting temperatures were set forth in the light of dam project features,and the temperature control measures and requirements are proposed such as mixer outlet temperature,placing temperature,lift thickness,interval period,co.

On the basis of the optimal selection of raw materials of concrete,we formulated rational temperature control measures in summer and winter,which had gained good effectiveness.

Consequently,the temperature control measures are adopted,such as rationalizing the construction sequence,optimizing the concrete mix proportion,controlling the concrete temperature when placing it to the working area,add.

,aiming at the optimization of technology and economy,the paper studies systematically the feasibility of applying different temperature control measures in different seasons and at different elevations;and obtains charac.

The result show that the concrete mixed with MgO can obviously compensate for thermal stress of the foundation restraint section and it is the useful way to simple temperature control measures and reduce thermal s.

Application of temperature control measures on high performance pumped-concrete to Ⅲ bid section of Caohe Aqueduct

In the construction,the integral temperature control approaches,such as material pre-cooling technique,cold water-mixing,ice-mixing,sun proofing and outside lowering are used to prevent the pier from crack to ensure constructing quality.

Based on domestic advanced experiences,practical temperature control measures were taken to ensure the construction quality.
