The research on bound rubber and reinforcing effect of mineral filler showed that there are four kind of interactions between filler and rubber matrix in uncured mix The unbounded rubber on the surface of filler will solve in organic solvent The rubber bounded by stronger physical or chemical interaction with filler will dissolve in organic solvent The bound rubber on the surface of filler by different extent acid-base interactions will solve in basic organic solvent The bound rubber on the surface of filler by chemical action (no acid-base type) will dissolve in basic organic solvent

结合橡胶和增强作用的研究表明，在混炼胶中，硅橡胶与矿物填料的作用形式有四种。没有联结在矿物表面的非结合橡胶和仅靠物理吸附联结在填料表面的硅橡胶将溶解于有机溶剂；与填料有较强相互作用的硅橡胶不溶于有机溶剂；通过不同层次的酸碱作用联接在矿物表面的硅橡胶将溶解于碱性有机溶剂；与填料有牢固化学结合的硅橡胶不溶于碱性有机溶剂。

According to a series of experiments such as cement mortar flowability,strength and chemically combined water,the hydration performance of composite cement-based materials containing Ultra-fine Fly Ash was studied.

通过水泥胶砂流动性、强度及化学结合水量试验，研究了超细粉煤灰水泥基复合胶凝材料的水化性能。

The proper alkaline content was in favor of compressive strength. The chemically combined water of paste without activator decreases with the increase of fly ash content, the content of Ca2 decreases after 28d. The increase extent of chemically combined water of pastes with NaOH is higher than that of without activator, and the paste with Ca2 is the same. The XRD peak of Ca2 of paste without activator is high at early age, and the peak of mullite and quartz has less change along with age. When NaOH is added, the peak of quartz of fly ash has clear drop. The surfaces of fly ash activated has eroded trace at 7 d.

研究结果表明：适量碱的掺入对强度有利；未掺激发剂浆体的化学结合水量随着粉煤灰掺量的增加而减少，Ca2含量在28d后开始下降；掺NaOH浆体的结合水量随龄期增长的幅度比未掺激发剂的浆体的大，而掺Ca：试样变化较小；未掺激发剂的水泥－粉煤灰体系在早期Ca2的峰值较大，且粉煤灰中的莫来石和石英晶体的衍射峰随龄期变化不大；NaOH掺入后，28d时，粉煤灰中的石英晶体衍射峰明显下降；时于掺激发别的试样，在7d时粉煤灰颗粒表面已被腐蚀。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.
