目前對濟(jì)南抹面砂漿的出廠檢驗(yàn)包括初凝時間、抗壓強(qiáng)度、密度、稠度和收縮率。抹面砂漿相關(guān)標(biāo)準(zhǔn)、規(guī)范有三個：《蒸壓加氣混凝土用砌筑砂漿與抹面砂漿》、《建筑砂漿基本性能試驗(yàn)方法》、《水泥膠砂干縮試驗(yàn)方法》。性能測試為材料的標(biāo)準(zhǔn)稠度、砂漿的保水性、分層度及砂漿的流動性四個方面。

At present, the factory inspection of Jinan plastering mortar includes initial setting time, compressive strength, density, consistency, and shrinkage rate. There are three standards and specifications related to plastering mortar: "Masonry mortar and plastering mortar for autoclaved aerated concrete", "Basic performance test method for building mortar", and "Dry shrinkage test method for cement mortar". Performance testing includes four aspects: standard consistency of materials, water retention of mortar, layering degree, and fluidity of mortar.

性能測試

performance testing 

(1)材料的標(biāo)準(zhǔn)稠度

(1) Standard Consistency of Materials

干拌砂漿按具體的設(shè)計(jì)標(biāo)準(zhǔn)用水量加水混合后，按規(guī)定方法攪拌均勻。以此判斷材料的性能，是否達(dá)到設(shè)計(jì)要求。方法原理是抹灰砂漿的濕砂漿對標(biāo)準(zhǔn)試桿(或試錐)的沉入具有一定阻力，通過試驗(yàn)濕砂漿的沉入度，確定砂漿的基本性能是否符合出廠要求。

After mixing the dry mixed mortar with water according to the specific design standards, mix it evenly according to the specified method. To determine whether the performance of the material meets the design requirements. The principle of the method is that the wet mortar used for plastering has a certain resistance to the sinking of the standard test rod (or cone). By testing the sinking degree of the wet mortar, it is determined whether the basic performance of the mortar meets the factory requirements.

(2)砂漿保水性

(2) Water retention of mortar

砂漿混合物能夠保持水分的能力稱為保水性。保水性也指砂漿中各項(xiàng)組成材料不易分離的性質(zhì)。

The ability of a mortar mixture to retain moisture is called water retention. Water retention also refers to the properties of various constituent materials in mortar that are difficult to separate.

(3)分層度

(3) Stratification degree

砂漿的保水性是用分層度表示的。攪拌均勻的砂漿靜置30min后，上下層砂漿沉入量的差值，稱為分層度。

The water retention of mortar is expressed by the degree of layering. The difference in the settling amount of the upper and lower layers of mortar after the evenly mixed mortar is left to stand for 30 minutes is called the layering degree.

(4)砂漿的流動性

(4) The fluidity of mortar

砂漿的流動性也叫稠度，是指在自重或外力作用下流動的性能。施工時，砂漿鋪設(shè)在粗糙不平的磚石表面上，要能很好地鋪成均勻密實(shí)的砂漿層，抹面砂漿要能很好地抹成均勻薄層，采用噴涂施工需要泵送砂漿，都要求砂漿具有一定的流動性。

The fluidity of mortar, also known as consistency, refers to its ability to flow under self weight or external forces. During construction, the mortar should be laid on a rough and uneven surface of bricks and stones, and it should be well laid into a uniform and dense mortar layer. The plastering mortar should be well spread into a uniform thin layer. Spraying construction requires pumping the mortar, which requires a certain degree of fluidity.

砂漿的流動性和許多因素有關(guān)，膠凝材料的用量、用水量、砂粒粗細(xì)、形狀、級配，以及砂漿攪拌時間都會影響砂漿的流動性。干拌砂漿濕砂漿的流動性可在實(shí)驗(yàn)室中，用砂漿稠度儀測定其稠度值(即沉入量)來表示砂漿的流動性。

The fluidity of mortar is related to many factors, such as the amount of cementitious materials, water consumption, sand particle size, shape, grading, and mortar mixing time, which all affect the fluidity of mortar. The flowability of dry mixed mortar and wet mortar can be measured in the laboratory using a mortar consistency meter to indicate the flowability of the mortar.

傳統(tǒng)砂漿流動性的選擇與砌體材料及施工天氣情況有關(guān)。對于多孔吸水的砌體材料和干熱的天氣，則要求砂漿的流動性要大些。相反對于密實(shí)不吸水的材料和濕冷的天氣，可要求流動性小些。

The selection of traditional mortar fluidity is related to masonry materials and construction weather conditions. For porous and water absorbing masonry materials and dry and hot weather, the fluidity of mortar is required to be greater. On the contrary, for dense and non absorbent materials and humid and cold weather, lower fluidity can be required.

而擁有良好保水性能的干拌砂漿的流動性可基本穩(wěn)定在一個相對標(biāo)準(zhǔn)的稠度范圍。還有什么疑惑或者問題，都可以隨時來我們網(wǎng)站http://m.man5g.cn咨詢！
