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.

本文介紹亞硫酸鹽酒精液滓塑化劑實驗室中的試製以及對於水泥膠砂及混凝土技術性能方面的作用。首先說明一些塑化劑的理論及亞硫酸鹽酒精液滓的技術規格,再簡要的介紹上海市政工程局材料試驗研究所試驗研究的經過和結果;最后综合蘇聯對於塑化劑和塑化水泥使用的先進經驗。塑化剂是一種有機的表面活動性物質,利用造紙工業发液進行酒精發酵所得的液滓。加入微量的塑化劑——約為水泥重量的0.1—0.25%,可以顯著的改善膠砂和混凝土的性質。在增加流動性、改善和易性和提高耐久性方面,有十分的效用,尤其是對節約水泥用量有极大的意義。祖國的建设事業正迫切需要這類新型的建築材料,因此提供一些试驗研究結果,以供国家主管機關和科技工作同志們深入研究和推廣使用時的參考。

In this paper, a survey is made over the existing theories of seismic forces onstructures. It is found that all the theories fall into one of the following cate-gories: 1) the so-called "statical theory" which considers the structure subject toan equivalent constant acceleration; 2) theories based upon simulated simplified ground motions; 3) theories based upon recorded actual ground motions; 4) theories based upon random impulses.

In this paper, a survey is made over the existing theories of seismic forces onstructures. It is found that all the theories fall into one of the following cate-gories: 1) the so-called "statical theory" which considers the structure subject toan equivalent constant acceleration; 2) theories based upon simulated simplified ground motions; 3) theories based upon recorded actual ground motions; 4) theories based upon random impulses. Critical comments have been given to the above theories, especially to thefourth one. The writer further gives a brief but cpmplete description of the responsespectra of the structure and on this basis, all the theories are co-related. Computations made by G. W. Housner for major American earthquakes dis-close that the acceleration spectra for damped system are flat curves withoutoutstanding peak value. For this reason, the writer deems that for certain typeof structures, variation of the acceleration spectral value for different modes of vibration will be small, and may be taken approximately as a constant. As aresult, the seismic forces reduce to this constant spectral acceleration times the.mass of the structure. It is suggested to use this method for estimatingthe base shear but make proper adjustment in its distribution along the height ofthe structure. It is also proposed to tie up this spectral acceleration to the earth-quake intensity scale. Finally, the writer stresses that further development of the theory of seismicforces on structures depends upon researches along following lings: 1) strong-motion program; 2) dynamical properties of structures and materials; 3) effectsof foundation conditions; 4) vertical and torsional seismic forces; 5) co-relationbetween seismic forces and earthquake intensity.
