Cement Paste

定义 Definition

cement paste 指由水泥与水(有时含少量外加剂/掺合料)拌合形成的浆体,在混凝土中用于包裹骨料并胶结各组分;其流动性与水灰比密切相关。(注:在材料学语境下常译为“水泥浆/水泥净浆”。)

发音 Pronunciation (IPA)

/smnt pest/

例句 Examples

Fresh cement paste must be mixed thoroughly before it begins to set.
新拌水泥浆在开始凝结前必须充分搅拌均匀。

A lower water-to-cement ratio can make the cement paste denser, improving strength but reducing workability.
较低的水灰比会使水泥浆更致密,从而提高强度,但会降低和易性。

词源 Etymology

cement 源自拉丁语 caementum(意为“碎石、石料”,后引申为“胶结材料”),经法语进入英语;paste 源自拉丁语 pasta(“面团、糊状物”),用于表示可涂抹的稠厚混合物。组合成 cement paste,字面即“水泥糊/浆”,在工程语境中特指水泥与水形成的胶结浆体。
