| Abstract: | Research purposes:A complete program related to materials option,grouting way,tested temperature control and maintenance of mass concrete in construction of cap of pile trestle is presented for the purpose of avoiding the appearance of crack in mass concrete caused by the temperature and other factors. Research results:The theoretical prediction and real site tests of the inner temperature of the concrete and real quality of the cap of pile trestle show this technique can control temperature cracking of mass concrete effectively. |
