摘要對呼和浩特市財政局辦公樓12層以上框架主體混凝土工程的研究,摻防凍劑和綜合蓄熱法的冬季施工措施,以及在施工過程中的具體控制辦法,降低了造價,保證了混凝土不被受凍破壞。In harsh climate region, the air temperature changes greatly between winter and summer. rcc dam are usually placed without bulk and longitudinal joints, and left free in winter. thus, it ' s unique thermal stress time - space distribution rule increases the difficulty of temperature control and crack control of rcc dam
由於嚴寒地區冬季氣候寒冷、年內氣溫變化幅度大;碾壓混凝土壩採取通倉澆築、不分縱縫以及越冬長間歇式的施工方法,使其具有獨特的溫度應力時空分佈規律,更增加了碾壓混凝土壩溫控與防裂難度。According to plentiful of experimentation, some new build techniques are created, for example the technique of no watering fill in winter, the technique of prevent frostbite and crack of faceplate etc. these techniques were proved by the project of lianhua cfrd. at last this paper gives some conclusion
而且根據地區特點,進行了大量的實驗,給出了以往一般面板壩所未遇到過的施工工藝,如冬季堆石體不灑水填築、面板的防凍抗裂、壩體渡汛措施等以及採用新的爆破方法開採石料等新的施工工藝。The conclusion shows the method fits and the mineral admixture can reduce the pore porosity of concrete and improve the compactibility and freezing resistance of concrete
結論對于混凝土冬季施工更合適未用自然變低溫養護的方法,摻入適量的摻合料能使混凝土孔隙率顯著降低,使混凝土更加密實,提高混凝土的抗凍性。分享友人
