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。

利用竹材做建筑物代替钢材及木材,在今天祖國社会主義建設有著重大的意義。竹材的性能在許多方面有其优点的,但是也還有许多缺点。(如中空端头、收縮开裂、易腐及生虫等。)假如不能克服其缺点,則其优点是不能很好利用的。本文针对竹材的中空端头、收縮开裂等缺点進行改造加工。通过試驗及研究證明:利用酪素—水泥膠把廢木料圆(?)或木板膠入竹桿或竹片端头或有節点处,这样竹桿件所制造出的各种型式竹結構是完全类似木結構的,可以說由構造上解决了結合困难,並且有了安全的保証。本文首先介紹了此型竹結結構的各种图式及合适跨度(图1),然后介紹竹桿的基本改選方法(圖3)及各式節点的構造方案(圖4),以及其簡單計算的举例(§2-7);最后简要介紹有关改造加工的施工工藝(§3)。本文認为若用作过防腐及防虫处理的竹材,再通过以上改造所制造的竹結構会能够比較安全的長期使用。(半永久性的而不再是臨时性的建筑。)
