一般对单色大理石要求颜色均匀；彩花大理石要求花纹、深浅逐渐过渡；图案型大理石要求图案清晰、花色鲜明、花纹规律性强。之，花色美观、便于大面积拼接装饰、能够同花色批量供货为好。矿物组成及主要特征大理石的矿物组成及矿石特征直接关系到其制品的使用性能和装饰效果。化学成分及物理性能大理石的化学成分对其能否被利用，一般不起主要作用，但能直接说明岩性，并间接影响物理化学性质，对大理石的可加工性、抗风化耐腐蚀的评价有一定意义。宁河柱塞泵型号A10VSO71DRG/31L-P

混凝土坍落度过大，混凝土产生离析，粗骨料集中而导致堵管。混凝土初浇时，导管下口距孔底太近、孔内泥浆落淤大，止水栓排不出导管形成堵管。混凝土浇筑方法不当、运输能力差，浇筑速度慢或中断时间长，管内混凝土流动性能丧失导致堵管。第四标段144槽堵管原因主要是冬季施工，混凝土内有较大冻结块，料口把关不严而造成的。堵管预防措施槽孔清孔时保证良好的泥浆，防止清孔过后落淤过大；导管底口距离孔底要符合设计要求；浇筑时溜槽口注意把关，防止径的团块、骨料进入导管；保证混凝土的质量和供应强度，组织协调好各环节的施工，确保浇筑混凝土的进度的连续性和均衡性。
