5. Results and discussion
The measured autogenous deformation for the mixtures is provided in Figs. 3 and 4. Deformations were recorded for 28 days. The deformations were zeroed at the moment of final setting time, according Table 2. The inflections of the curves that occurred between 1 and 2 days may be due to the following effects; reabsorption of detrimental bleeding water accumulated at very early age between paste and the corrugated tube; ettingite needles growth; crystals of calcium hydroxide growth; topochemical reaction of C3S. However, the origin of this swelling was not investigated.
As shown in Fig. 3, RHA could decrease the autogenous deformation. With no RHA, a considerable autogenous deformation, approximately 600 lm/m, is developed during 4 weeks of sealed hardening. Replacement of 5% and 10% of Portland cement by RHA lead to a successive reduction of this autogenous deformation. At 10% RHA could decrease the autogenous deformation after 4 weeks by 250 lm/m.
RRHA provides a positive effect on the autogenous deformation, since early ages (1–2 days) which is attributed to the filler effect, when compared with the hydration effect of an equal dosage of Portland cement. The humidity measurements, Fig. 5, confirm a higher humidity of paste with RRHA. The cement substitution by CRHA at early age increases the autogenous deformation due to the pozzolanic effect, since chemical shrinkage of the silica reaction is much higher than Portland cement reaction; but with time ,probably due to its cellular structure the autogenous deformation decreases in comparison with that of the paste without RHA (control).In the long time the behavior of the pastes with CRHA was similar to those of RRHA pastes. The lower strength of mixtures with CRHA is an indication of higher porous structure which may lead to lower capillary stresses in these pastes. The humidity values of the CRHA paste are higher than RRHA paste, which may also result of changes on porous structure. In fact, assuming that only Portland cement consumes water during hydration, the higher relative humidity of CRHA, when compared with RRHA, may be explained by the existence of larger pores in the CRHA paste.

The measured autogenous deformation for the mixtures is provided in Figs. 3 and 4. Deformations were recorded for 28 days. The deformations were zeroed at the moment of final setting time, according Table 2. The inflections of the curves that occurred between 1 and 2 days may be due to the following effects; reabsorption of detrimental bleeding water accumulated at very early age between paste and the corrugated tube; ettingite needles growth; crystals of calcium hydroxide growth; topochemical reaction of C3S. However, the origin of this swelling was not investigated. 关于混合物实测的自生变形，在图3和图4中提供。变形情况记录了28天。根据表2，在最后凝固时的瞬间，变形归零。在1天和2天之间发生的曲线的弯曲变化可能是由以下效应引起的：在浆体和皱纹管之间很早阶段累积的，有害的泌水的重吸收；钙矾石（这里ettingite可能应该是ettringite）针状物的生长；氢氧化钙晶体的生长；C3S的拓扑化学反应。不过这一隆起的起因尚未得到研究。
As shown in Fig. 3, RHA could decrease the autogenous deformation. With no RHA, a considerable autogenous deformation, approximately 600 lm/m, is developed during 4 weeks of sealed hardening. Replacement of 5% and 10% of Portland cement by RHA lead to a successive reduction of this autogenous deformation. At 10% RHA could decrease the autogenous deformation after 4 weeks by 250 lm/m. 如图3所示的那样，RHA可以减小自生变形。在没有RHA情况下，在4周的密封硬化过程中，会发展相当大的自生变形，大约达600 lm/m。在10％情况下，RHA能在4周后使自生变形减小250 /m.
RRHA provides a positive effect on the autogenous deformation, since early ages (1–2 days) which is attributed to the filler effect, when compared with the hydration effect of an equal dosage of Portland cement. The humidity measurements, Fig. 5, confirm a higher humidity of paste with RRHA. The cement substitution by CRHA at early age increases the autogenous deformation due to the pozzolanic effect, since chemical shrinkage of the silica reaction is much higher than Portland cement reaction; but with time ,probably due to its cellular structure the autogenous deformation decreases in comparison with that of the paste without RHA (control). RRHA （从早期（1－2天）起）对自生变形提供正面的影响，这归因于与相同剂量波特兰水泥的水合作用影响相比时，填充剂的影响。图5中的湿度测量值证实了采用RRHA的浆体较高的湿度。用CRHA取代水泥在早期阶段，因为火山灰（凝硬）效应会使自生变形增加，因为二氧化硅反应的化学收缩大大高于波特兰水泥反应的；但是随着时间，或许由于其蜂窝状结构，所以自生变形相比于不含RHA（控制的）浆体的会下降。In the long time the behavior of the pastes with CRHA was similar to those of RRHA pastes. The lower strength of mixtures with CRHA is an indication of higher porous structure which may lead to lower capillary stresses in these pastes. The humidity values of the CRHA paste are higher than RRHA paste, which may also result of changes on porous structure. In fact, assuming that only Portland cement consumes water during hydration, the higher relative humidity of CRHA, when compared with RRHA, may be explained by the existence of larger pores in the CRHA paste. 在长时间中，采用CRHA的浆体的性状与RRHA浆体的相似。采用CRHA的混合物较低的强度表明了其较高的多孔性结构，这可能在这些浆体内导致较低的毛细管应力。CRHA浆体的湿度值高于RRHA的，这也可能是多孔结构变化的结果。事实上，假设在水合作用过程中，只有波特兰水泥消耗水，那么当与RRHA想比时，CRHA较高的相对湿度就可得到解释，即CRHA浆体中存在较大的气孔。
