Plasticizing agent is an organic surface-active admixture for cement mortar and concrete. It may be introduced also as an "addition" to the clinker during the grinding process in the manufacture of plasticizing Portland cement. In the USSR, the plasticizing agent under the name of "has been extensively and successfully used in construction works.The plasticizing agent is prepared by chemical treatment of the waste from the alcoholic fermentation of sulfite liquor in pulp manufacture. It contains calcium lignin sulphonate as an effective component and thus possesses hydrophilic property. Due to the adsorption of the agent, a colloidal layer is formed on the surface of the cement particle; hence the effective dispersion and the increase of lubricity between the particles.Following the Soviet experience of CCB, the Materials-Testing and Research Laboratory of Shanghai Civil Engineering Bureau successfully experimented with the preparation of thermal polymer of the plasticizing agent, and a series of tests on the characteristics of the agent were made. This paper attempts to describe the method of preparation and the main properties of the agent.The addition of the agent in an amount of 0.1—0.2% of cement (dry weight) markedly improves the workability and the texture of the mortar and concrete mixtures. It reduces the water requirement and the cement content. It improves the impermeability and durability of the hardened mortar and concrete.The agent has a retarding effect on the setting of cement. It lowers the early strength of mortar and concrete, while the strength of later age is higher than those without admixtures. The use of CaCl_2 accelerator in 0.5—1% of cement by weight speeds up the rate of development of the early strength.The proper dosage of the agent depends upon the properties of cement. Therefore, certain tests should be made with the specified cement and aggregates on the job before the adoption of the agent.

This paper studies the new technology of alcoholic fermentation of uncooked corn meal by using glucoamylase derived from Aspergillus niger is studied. With this technology,it is unnecessary to gelatinate corn starch by heating and to liquefy corn starch with α-amylase. And only adding of 500 units of the glucoamylase per gram corn meal, same result will be shown like that of the present 80℃ corn meal low-temperature cooking and high-pressure cooking. It is found that the yield of ethanol from corn meal will be reduced if more glucoamylase, in which transglucosidase exists, is used,The estimated economic result showes that the key to expend the technology in large scale lies in reducing production cost,although the new technology has the advangtages of energy-saving, easy operation.

本文研究了利用黑曲糖化酶糖化生玉米粉进行酒精发酵的新工艺。该技术不需要加热糊化和添加α-淀粉酶液化,仅要求糖化酶用量为500单位/每克玉米粉即可达到与成熟的玉米粉80℃低温蒸煮和高压蒸煮酒精生产技术相同的发酵水平。但因糖化酶中含有转苷酶,发现如过多添加糖化酶会引起酒精产率下降。进一步的经济效益估算表明,生玉米粉酒精发酵技术虽然节省了大量能源,简化了操作工序,但要在工业上推广应用,关键还在于要降低生产成本。
