水泥搅山制作为什么会开裂

来源:  更新时间:2022-05-13
水泥假山能不能仿真模拟,在于石材表面抹灰层的材料,颜色和施工技术水准.要仿真模拟就需要尽可能选用同样的颜色,并根据用心抹灰,对石材表面的裂纹和边角开展用心营造,使石材表面具备真实的层次感,以做到“要是”的实际效果。
Whether the cement rockery can be simulated depends on the material, color and construction technology level of the plastering layer on the stone surface To simulate, we need to choose the same color as much as possible, and plaster according to the heart, and carefully create the cracks and corners on the stone surface, so as to make the stone surface have a real sense of hierarchy, so as to achieve the actual effect of "if".
抹灰用的水泥砂浆应依据仿岩型原有的颜色上色,并应添加一些色浆。
The cement mortar for plastering shall be colored according to the original color of rock imitation type, and some color paste shall be added.
假如要模仿灰黑色岩层,可在一般深灰色水泥砂浆中添加碳黑,黑灰色水泥砂浆中添加墙泥,要模仿淡黄色板岩,水泥砂浆中应添加青柠檬氧化铁黄,要模仿蓝紫色板岩,务必用氧化铁红将水泥砂浆调成紫砂壶色,而模仿青石板的水泥砂浆中可添加氧化铬绿和钴蓝,配置五颜六色水泥砂浆时,水泥砂浆的颜色应比设计方案颜色稍深,成形成岩层后其颜色会稍浅。
If you want to imitate the grayish black rock stratum, you can add carbon black to the general dark gray cement mortar, add wall mud to the black gray cement mortar, imitate the light yellow slate, add green lemon iron oxide yellow to the cement mortar, and imitate the blue purple slate, be sure to use iron oxide red to adjust the cement mortar into the purple sand pot color, while the cement mortar imitating the bluestone slate can add chromium oxide green and cobalt blue to the cement mortar, and when configuring the colorful cement mortar, The color of cement mortar shall be slightly darker than that of the design scheme, and the color will be slightly lighter after forming the diagenetic layer.
塑石假山的具体原材料是建筑钢筋混凝土,而造成塑石假山裂开的根本原因便是混凝土。塑石假山成形后,在初期抗压强度并未充足产生之前,因为混凝土的湿胀干缩,化学缩减,热涨冷缩等因素形成了收拢,无拘无束的水泥混凝土通常会造成裂缝。
The concrete raw material of plastic stone rockery is building reinforced concrete, and the fundamental reason for the crack of plastic stone rockery is concrete. After the plastic stone rockery is formed, before the initial compressive strength is not sufficient, it is closed due to factors such as wet expansion and dry shrinkage, chemical shrinkage, thermal expansion and cold shrinkage of concrete. Unrestrained cement concrete usually causes cracks.
大容积塑石假山因为构造规格大,混凝土水胶比造成的塑石假山身体内温度上升,发热量不容易立即释放而产生很大的温度差别,比较大的温度转变和差别造成混凝土容积的转变,因为塑石假山各位置不一样水平地遭受管束,不可以随意伸缩式,当温度形变造成的拉应力超过水泥混凝土抗压强度时,便造成了裂缝,欲清裂缝,务必从降低水泥混凝土干缩下手。
Due to the large structural specifications and the water binder ratio of concrete, the temperature in the plastic stone rockery body increases, and the calorific value is not easy to release immediately, resulting in a great temperature difference. The relatively large temperature change and difference cause the change of concrete volume. Because the plastic stone rockery is subject to tube bundles at different levels, it is not allowed to expand and retract at will. When the tensile stress caused by temperature deformation exceeds the compressive strength of cement concrete, It will cause cracks. If you want to clear the cracks, you must start from reducing the dry shrinkage of cement concrete.
