REGULATION OF HYDRATION PRODUCTS OF CEMENT DURING HARDENING

第二届北京国际水泥及混凝土学术会议

作者： Kolbasov Valentin Vasilenko Irina Moskow Chemical-Technology Institute after D.I.Mendeleev MoskowUSSR

Having studied regularities of structure transformations of cement stone in the process of its hardening as a result of the influence of composition and properties of cements themselves as well as the influence of conditions of application viz. temperature and moisture conditions of the hardening medium,value of w/c factor,presence of water-soluble admixtures of different purposes and so on,we have theoretically developed,experimentally verified and realized in practice some postulates supporting primary importance of distribution of hydrates in the cement stone *** have also developed some methods of operation and control of these processes.

Analysis in Theory and Applications 1992年第3期8卷 51-61页

作者： A.Shadrin Computing Center Siberian Branch Academy of Sciences of the ussr prospekt akademika Lavrentieva 6 Novosibirsk 630090 Russia Post address:Shadrin A.Yu.Morskoi prospekt 3 f1.14 Novosibirsk 630072 Russia

The following theorem is proved Theorem *** q be a polynomial of degree n(qP_n)with n distinct zeroes lying in the interval[-1,1] and △'_q={-1}∪{τ_i:q'(τ_i)=0,i=1,n-1}∪{1}. If polynomial pP_n satisfies the inequality then for each k=1,n and any x[-1,1]its k-th derivative satisfies the inequality 丨p^(k)(x)丨≤max{丨q^((k))(x)丨,丨1/k(x^2-1)q^(k+1)(x)+xq^((k))(x)丨}. This estimate leads to the Markov inequality for the higher order derivatives of polynomials if we set q=T_n,where Tn is Chebyshev polynomial least deviated from zero. Some other results are established which gives evidence to the conjecture that under the conditions of Theorem 1 the inequality ‖p^((k))‖≤‖q^(k)‖holds.
