,this article discusses the possibility of RCC dam construction with layer thickness of 50 cm,and puts forward the proposal of increasing slump,reducing the difficulty of abnormal concrete vibrating a.

As a primary control device of abnormal concrete grout-sprinkling machine, miniature PLC block LOGO! which is made by SIEMENS can simplify control system for that any other control elements are not necessary, only 12V direct current supply is needed .

Aiming at the main relative factors of separately continuously changing the pouring mode, pouring quantity,each layer thickness and vibration equipment of abnormal concrete construction at the different rising layers and the different poured positions,the article observes the appearance quality of abnormal concrete after the formwork is dismounted.

Application of metamorphic concrete in the construction of the RCC dam for Jiangya Water Control Project;

Application of metamorphic concrete to roller compacted concrete dam projects;

Through the analysis on a lot of indoor and engineering experimental results on RCC,this paper presents the technical methods through mixing,spraying and painting,which took consider into the following factors: mineral fiber distorted concrete,interbedded binding material,impervious crystal seepage control pa.
