目前对济南抹面砂浆的出厂检验包括初凝时间、抗压强度、密度、稠度和收缩率。抹面砂浆相关标准、规范有三个：《蒸压加气混凝土用砌筑砂浆与抹面砂浆》、《建筑砂浆基本性能试验方法》、《水泥胶砂干缩试验方法》。性能测试为材料的标准稠度、砂浆的保水性、分层度及砂浆的流动性四个方面。

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.

性能测试

performance testing 

(1)材料的标准稠度

(1) Standard Consistency of Materials

干拌砂浆按具体的设计标准用水量加水混合后，按规定方法搅拌均匀。以此判断材料的性能，是否达到设计要求。方法原理是抹灰砂浆的湿砂浆对标准试杆(或试锥)的沉入具有一定阻力，通过试验湿砂浆的沉入度，确定砂浆的基本性能是否符合出厂要求。

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)砂浆保水性

(2) Water retention of mortar

砂浆混合物能够保持水分的能力称为保水性。保水性也指砂浆中各项组成材料不易分离的性质。

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)分层度

(3) Stratification degree

砂浆的保水性是用分层度表示的。搅拌均匀的砂浆静置30min后，上下层砂浆沉入量的差值，称为分层度。

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)砂浆的流动性

(4) The fluidity of mortar

砂浆的流动性也叫稠度，是指在自重或外力作用下流动的性能。施工时，砂浆铺设在粗糙不平的砖石表面上，要能很好地铺成均匀密实的砂浆层，抹面砂浆要能很好地抹成均匀薄层，采用喷涂施工需要泵送砂浆，都要求砂浆具有一定的流动性。

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.

砂浆的流动性和许多因素有关，胶凝材料的用量、用水量、砂粒粗细、形状、级配，以及砂浆搅拌时间都会影响砂浆的流动性。干拌砂浆湿砂浆的流动性可在实验室中，用砂浆稠度仪测定其稠度值(即沉入量)来表示砂浆的流动性。

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.

传统砂浆流动性的选择与砌体材料及施工天气情况有关。对于多孔吸水的砌体材料和干热的天气，则要求砂浆的流动性要大些。相反对于密实不吸水的材料和湿冷的天气，可要求流动性小些。

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.

而拥有良好保水性能的干拌砂浆的流动性可基本稳定在一个相对标准的稠度范围。还有什么疑惑或者问题，都可以随时来我们网站//www.gochiism.com咨询！
