This paper first discusses the cause of crack formation and crack mechanism of high performance concrete. then carries out crack tests of three groups of concrete slabs using aggregate type, sand rate and dosage of fly ash as design parameter
本文初步探討了泵送高流態混凝土的裂縫成因和開裂機理，並分別以骨料品種、砂率以及粉煤灰摻量為設計參數進行了三組配合比混凝土平板的抗裂試驗。Under different sand ratio, the relationship between water cement ratio and 28 day compressive strength is researched and the coefficient of recycled concrete is induced
在不同砂率下，分析了再生混凝土28天齡期抗壓強度與水灰比之間的關系，並回歸分析得出了再生骨料系數。Some respects of self - compacting high - strength concrete ( schsc ) made of fujian province ' s local material have been studied in this thesis as follows : 1. studies on microstructure of the schsc. three different mixed schsc and one normal high - strength concrete ( nhsc ) were observed by the scanning electron microscope at different sites and different ages of 1 day, 3 days, 7 days, 28 days and 60 days. from the test, the effects due to no vibrating and admixture on the microstructure of schsc were studied
通過四組強度等級相當，分別為普通混凝土、兩組不摻膨脹劑的自密實混凝土（其粉煤灰的摻量不同）和摻有膨脹劑的自密實混凝土，在同一養護齡期的條件下（ 1天、 3天、 7天、 28天和60天） ，分別選擇粗骨料過渡區、細骨料過渡區、水泥石和砂坑作為觀測點，採用sem進行細觀掃描對比實驗，以研究自密實混凝土因免振搗的特性及摻合料對其骨料界面和水泥石結構的影響。The traditional way of sandstone correlation based on the geometrical similarity of well - logs which emphasizes " based on the cycle and correlating from larger to smaller " has shown its theoretical limits when explaining the correlating and the scale, geometry, continuity, connectivity of sandstones and the law of the reservoir property. it has been an urgent and difficult subject to find new theory and methods to solve the reservoir correlation and property prediction. it ' s a new way to correlate strata and found framework of reservoir through the process - response analysis in the base - level cycles
儲層骨架模型是建立儲層地質模型的前提和關鍵，建立在測井曲線相似性基礎上的傳統「旋迴控制，分級對比」原則在進行高含水期精細對比時表現出地層學理論依據不足，在解釋小層段的砂體對比方面，在解釋不同層位砂體規模、形態、砂體連續性、連通性和儲層物性的變化規律方面缺乏有力的理論支撐。By uses of handan raw materials, this paper studies the influence of coarse aggregate limiting grain size, water - binder ratio, fly ash replacement, sand - total aggregate ratio on the strength and workability of concrete prepared with low water - binder ratio
摘要本試驗採用邯鄲當地的混凝土原材料，利用正交設計方法，試驗研究和分析了粗骨料最大粒徑、水膠比、粉煤灰摻量、砂率對低水膠比混凝土的強度及和易性的影響。分享友人
