It provided the reference to improve the anti-cracking capability of high strength and high performance concrete from the point of view of constructional technology and curing requirement.The result shows that the more the binder material or sand rate, the more serious the shrinkage cracking. In the concrete with a low water-to-binder ratio, a bit of difference in the dosage of water will result in big difference on the strength and the anti-cracking capability. The occurrence of cracking is mainly at early age (before 1 day). If the surface is plastered again after 2 hours of casting, the anti-cracking capability will nicely improved.

研究结果表明：随着胶结料总量和砂率的增大，高强高性能混凝土的收缩开裂趋于严重；在水胶比较低的情况下，用水量的稍微差别对混凝土的强度和抗裂性能都具有很大的影响；掺入粉煤灰对抗裂有所改善，但是其掺量对抗裂的影响并不是呈定向规律，而是存在着最优掺量；高强高性能混凝土的裂缝主要发生在早期(1d前)，若在浇注后2个小时再次抹面可以很好地改善其抗裂性能。

The major hydrate is CSH gel under this condition. Curing of mortar in water increases the hydration degree of the binder with or without thermal proceeding. In addition to more CSH gels, some ettringite is formed.

试样脱模后在60 ℃蒸养6 h将阻碍无水石膏向二水石膏转化，但促进粉煤灰的火山灰反应，此时主要水化产物是CSH凝胶；继续水养护进一步促进胶结材的水化，除生成较多CSH凝胶外，还有部分钙矾石生成。

Then the comprehensive diagenetic facies of the upper Triassic Xujiahe Formation are suggested also. It is concluded that that the compactionfracturesiliceous cementation facies of the thrust belts and the compactiondissolutionchlorite coating facies of foredeep zones are more favorable for hosting oil.

Through the methods of polarizing microscope and cathodoluminescence, the diagenesis of Late Carboniferous phylloid algal reefs in southern Guizhou is studied, which indicates diagenesis are mainly of bio-binding and baffling actions, micritization, cementation, compaction-pressure solution, fracture, recrystallization and dissolution in type.

东北大学资源与土木工程学院，沈阳110004通过偏光显微镜研究和阴极发光技术，对黔南晚石炭世叶状藻礁灰岩的成岩作用做了详细研究，认为礁灰岩主要成岩作用类型有：生物黏结障积作用、泥晶化作用、胶结作用、压实压溶作用、破裂作用、重结晶作用和溶解作用等。

Because the direct roof of the No.92 ore-body is the backfilling of the No.91orebody which is the cementing materials or non-cementing materials, and there are no-filled mined-areas in someplace. So there are large-scale hidden troubles on the top of the No.92 slowly inclined large and thick ore-body, then we must find a new mining technology which aims at the complex mining condition of the No.92 ore-body. The cutting nature of the No.92 ore-body is very poor, so choosing the rational drilling and blasting parameters and enhancing the overall technological economic benefits are also the urgent problems waiting to be solved in the exploitation of the No.92 ore-body. The No.92 ore-body, thin lodes and the exploitation process of the No.91orebody influence each other, the geo-pressure phenomena aggravates obviously in case of the mined-areas increase constantly, and the geo-pressure problem will be more and more serious when the No.92 ore-body be exploited on a large scale in the next step.

由于它的直接顶板就是开采91号矿体时的胶结或者非胶结的空区充填体，部分地段甚至是未充填的采空区，使92号缓倾斜厚大矿体的上部形成大范围的隐患区，因此，必须针对92号矿体复杂的开采技术条件，寻找新的采矿技术与工艺。92号矿体的可凿性极差，选择合理的凿岩爆破参数，提高凿岩爆破工作的总体技术经济效益，也是92号矿体开采急待解决的问题。92号矿体与细脉带、91号矿体开采相互影响，目前在采空区不断增大的情况下地压显现有明显加剧的趋势，在下一步92号矿体大规模开采时，地压问题将越来越严重。

When the sandstones are surrounded by carbonates or thick mudstones, then high carbonate contents will be found in the sandstones.
