wet concrete
1.Abstract: The basic mechanical properties of full mix concrete and its wet-screened concrete incorporating water-reducing agent and air entrained agent tested,such as compressive strength,tensile strength,compressive elastic modulus,tensile elastic modulus,ultimate tensile elongation,flexural characteristics and abrasion resistance,and the relationship of various mechanical properties for the two kinds of concrete is established.The results are important for mass full mix concrete,especially for concrete incorporating air entrained agent.
5.Wrap up the armored concrete and strengthen and use the most extensive one to be that the armored concrete axis is strengthened by the other wet cladding steel columns which presses the post outside, outside make armored concrete is it keep post whether one two receive strength the strength component to strengthen, including and strengthen two the last parts before strengthening.
6.The authors of this paper aimed at the present state in which the high quality dry fly ash suitably to used as the active admixture of high performance concrete is small and most of it is low class wet fly ash,developed the class 525R～625R special cement for high performance concrete adopted pre activated wet fly ash used as addition of cement,as well as by adding superplasticizer and limestone powder etc. admixture by orthogonal experiments.
7.The company has lots of senior engineers and professional technicians and it is engaged in the production of various wet valve electromagnet MFB1(Z1)-YC Series, Lex Series of Germany, Youyan electromagnet series, AC/DC dry electromagnet, explosive electromagnet series as well as electromagnet used for concrete conveying pump.
8.In this paper,starting from the basic law of fluid me chanics,a mathematical model equation for describing the tran sient flow of the wet gas in the pipeline under peak shaving op eration is established, a simplified treatment for the model equa tion is made and a train of thought for concrete calculation is de signed.
