抹面砂漿，它是為了后期裝飾使用的。所以說抹面砂漿都要求具有很好的和易性。這樣他可以便于以后施工。下面濟南抹面砂漿廠家來講講砂漿材料使用期間的性能測試。

Plastering mortar is used for later decoration. Therefore, plastering mortar is required to have good workability. In this way, it can facilitate future construction. Next, Jinan plastering mortar manufacturer will talk about the performance test of mortar materials during use.

(1)材料的標準稠度

(1) Standard consistency of material

干拌砂漿按具體的設計標準用水量加水混合后，按規定方法攪拌均勻。以此判斷材料的性能，是否達到設計要求。方法原理是抹灰砂漿的濕砂漿對標準試桿(或試錐)的沉入具有一定阻力，通過試驗濕砂漿的沉入度，確定砂漿的基本性能是否符合出廠要求。

The dry-mixed mortar shall be mixed with water according to the specific design standard, and then mixed evenly according to the specified method. To judge whether the performance of the material meets the design requirements. The principle of the method is that the wet mortar of the plastering mortar has certain resistance to the sinking of the standard test rod (or test cone). By testing the sinking degree of the wet mortar, determine 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組成材料不易分離的性質。

The ability of mortar mixture to retain water is called water retention. Water retention also refers to the property that the constituent materials in mortar are not easy 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。圖片

The water retention of mortar is expressed by the degree of stratification. After the evenly mixed mortar is left for 30min, the difference between the settlement of the upper and lower layers of mortar is called the layering degree. picture

(4)砂漿的流動性

(4) 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，砂漿鋪設在粗糙不平的磚石表面上，要能很好地鋪成均勻密實的砂漿層，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 called consistency, refers to the performance of flowing under the action of self-weight or external force. During construction, the mortar shall be laid on the rough and uneven masonry surface, which shall be well paved into a uniform and dense mortar layer, and the plastering mortar shall be well plastered into a uniform thin layer. The mortar shall be pumped for spraying construction, which requires the mortar to have a certain fluidity.

砂漿的流動性和許多因素有關，膠凝材料的用量、用水量、砂粒粗細、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驗室中，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. The amount of cementitious material, water consumption, sand size, shape, gradation, and mortar mixing time will affect the fluidity of mortar. The fluidity of dry-mixed mortar and wet mortar can be measured by the mortar consistency meter in the laboratory to indicate the fluidity of mortar.

傳統砂漿流動性的選擇與砌體材料及施工天氣情況有關。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。相反對于密實不吸水的材料和濕冷的天氣，可要求流動性小些。而擁有良好保水性能的干拌砂漿的流動性可基本穩定在一個相對標準的稠度范圍。

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 wet and cold weather, the fluidity can be required to be small. The fluidity of dry-mixed mortar with good water retention performance can be basically stabilized in a relatively standard consistency range.
