The elasticity polyurethane joint sealing material is one kind of joint sealing materials for concrete pavement joint which can use at normal temperature. It will solidify by chemic-reaction when commix the polyurethane preploymer, cross link agent, filling, plasticizer and catalyzer.

聚氨酯弹性嵌缝料是一种由聚氨酯预聚体主剂与交联剂、填料、增塑剂以及催化剂混合后通过化学反应交联固化的常温施工式水泥混凝土路面用嵌缝材料。

The results showed that compared with traditional fluorite and phosphorous slag, phosphorous slag composite mineralizer was effective on reducing amount of f-CaO in cement clinker and improving burnablity of raw meals, but the effect was still obvious when sintering temperature and sintering time were increasing. The analysis of XRD, SEM and petrographic structure showed that phosphorous slag composite mineralizer decreased viscosity of liquid, promotes the formation of Alite in clinker and improves crystal form and size of minerals.

结果表明，与传统的萤石和磷渣矿化剂相比，磷渣与萤石复合的矿化剂可有效降低水泥熟料中游离氧化钙的含量，改善生料的易烧性；在燃烧温度与时间增加的情况下，改善作用仍然明显；通过XRD、SEM与岩相结构分析表明，磷渣与萤石的复合矿化剂降低了液相的粘度，促进了A矿的生长，对矿物的结晶形态有改善作用，有利于晶体尺寸的生长发育。

In this paper, it mainly reaearch the gringding aids and mineralizer. The contents are as follows:In this paper, TEA, calcium lignosulphonate, DMF, NF-2, DEG and glycol are used as grinding aids and fly ash is selected for active composite material.

本文主要对水泥助磨剂和矿化剂进行了试验研究，具体内容如下：本文主要选用了三乙醇胺、木质素磺酸钙、DMF、高效减水剂NF—2、二甘醇和乙二醇作为助磨剂，选用粉煤灰作为活性混合材。

From original rosin heat aggregated air entraining agent and naphthalene-based water reducer to high performance water reducer,the concrete admixture plays an important role in improving concrete durability and construction quality,and reducing cement and water quantity of concrete.

从最初的松香热聚物引气剂，20世纪七八十年代发展起来的萘系等减水剂，到以后的高效减水剂，在提高混凝土耐久性和施工质量，减少混凝土单方水泥用量和用水量方面起到了非常重要的作用。

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。
