• Abstract : water - cement ratio is an important parameter in concrete proportioning design and has a great effect on the nature of concrete , such as its intensity and durability
  文摘:水灰比是砼配合比设计中一个重要参数，主要体现在其对砼性能(和易性、强度和耐久性等)的影响上。
• The concrete used in testing bridge is monitored and some performance at definite age including compressive strength , splitting fensile strength , frost resistance , scaling frost resistance , chloride ion diffusion coefficient ( dcl - ) , resistance of carbonization and pore structure by mercury porosimetry are tested . these performances are compared with that of concrete which designed by traditional method . the results show that mechanical properties of concrete designed by high durability concrete proportion and traditional method meet require ment at any age , however , frost resistance , scaling frost resistance , chloride ion diffusion coefficient ( dcl - ) , resistance of carbonization and pore structure of the former are better than the latter , so high durability concrete is economic benefit
  对试验桥用混凝土的质量进行监控,并成型试件测量所需龄期内的抗压强度、劈裂强度与抗冻融、抗盐冻、氯离子扩散系数( dcl - ) 、抗碳化等耐久性能指标及孔结构,并与传统混凝土进行对比研究,结果表明:高耐久性混凝土及按传统配合比设计的混凝土的力学性能均能满足相应龄期的要求,但前者的抗冻融性能、抗盐冻性能、抗碳化性能、 dcl -和孔结构明显优于后者,并具有明显的社会经济效益。
• In this paper , the influences on concrete shrinkage and splitting tensile strength by the varieties and contents of the raw materials , such as cement , sand , fly ash , water - reducer and expansion agents , are studied . the possibility of the prevention of the concrete cracking by proper concrete proportion design is discussed
  本文着重研究了水泥、砂、粉煤灰、减水剂、膨胀剂等材料的品种、用量对混凝土收缩性能及混凝土劈裂抗拉强度的影响，探讨了通过合理的配合比设计达到减少混凝土收缩、提高混凝土劈裂抗拉强度进而降低混凝土开裂风险的可能性。
• The expansion agents can only make up the shrinkage to some extent , and the compensation effects would be reduced when the retardener and fly - ash are used . the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness . under bad curing condition , the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property , while the nominal steels have very unobvious effects . to reduce the concrete shrinkage thus avoid the cracking , the former factors must all be taken into account in concrete proportion design to develop sound concrete
  研究结果表明，水泥的品种和用量是影响混凝土收缩值的主要因素之一，当混凝土中水泥用量超过470kg / m ~ 3时，混凝土的收缩值超过400 10 ~ ( - 6 ) ，在约束状态下存在高开裂风险；采用细砂使混凝土单位用水量显著提高，收缩值也大幅增加；优质粉煤灰总体上能抑制混凝土的收缩，以超量方式掺入其抑制作用更加明显，但粉煤灰混凝土早期的粘聚性较差，应注意养护，以免失水产生龟裂；早强减水剂和缓凝减水剂都会使混凝土收缩值增加；膨胀剂只能补偿混凝土部分收缩，同时受缓凝剂和粉煤灰的抑制，而且膨胀使混凝土的体积安定性增加了不确定因素，膨胀剂不是解决混凝土收缩裂缝的良方。
