In high performance concrete(HPC)mixed with Ordinary portland Cement(OPC),the clinker cannot hydrate completely because of coarse particles of clinker and low W/C ratio of HPC and therefore results in great waste of the clinker.In this paper,the ultrafine cement was used to mix with HPC to make full use of the clinker in it. At the same time large quantities of supplementary cementing materials(SCMs)such as ground granulated slag,fly ash and ground limestone were used to reduce the dosage of cement,decrease...

In high performance concrete(HPC)mixed with Ordinary portland Cement(OPC),the clinker cannot hydrate completely because of coarse particles of clinker and low W/C ratio of HPC and therefore results in great waste of the clinker.In this paper,the ultrafine cement was used to mix with HPC to make full use of the clinker in it. At the same time large quantities of supplementary cementing materials(SCMs)such as ground granulated slag,fly ash and ground limestone were used to reduce the dosage of cement,decrease the heat generation and avoid the strength regression of ultra fine cement.The mechanical properties and chemical attack resistance were mainly discussed in this paper.It's shown that fresh HPC mixed with the composite binder showed more workable than that mixed with OPC,but the flexural and compressive strengths of the former were less than that of the latter within one year.However,the strengths of the former HPC surpassed the latter after 365 days. Furthermore,the former HPC showed more chemical attack resistance,the decrease of strengths was still very low till 365 days' of immersion in very high concentration of chemical erosive solutions though the strengths show decreasing all the time.The composite binder can also be used to put up self consolidation HPC,the initial slump and slump flow value were all above 20cm and 58cm respectively when water content was 180kg/m 3~185kg/m\+3 and the dosage of SN Ⅱ was 1 0%~1 5%.Additionally,the slump loss and slump flow loss were all very small.

用普通水泥配制的高性能混凝土由于熟料粒度较大、混凝土水灰比较低而导致熟料有效利用率低 ,造成较大浪费 ,对环境保护不利。本文尝试采用超细水泥配制高性能混凝上 ,以提高水泥熟料的有效利用率 ,并复合掺加矿渣、粉煤灰和磨细石灰石粉等混合材以减少水泥用量、降低超细水泥水化热 ,防止强度倒缩等 ,并着重研究了超细水泥高性能混凝土的力学性能和抗化学侵蚀性能。结果表明 ,用超细水泥复合胶凝材料配制的高性能混凝土在配合比相同情况下 ,和易性优于普通水泥高性能混凝土 ,其抗压强度在一年龄期内同龄期强度均小于普通水泥高性能混凝土 ,但至 365d时强度已赶上后者。抗硫酸盐侵蚀和抗硝酸氨侵蚀性能很强 ,在SO2 - 4和NH4 NO3浓度很高的溶液中浸泡一年后 ,强度基本呈下降趋势 ,但下降幅度不大。超细水泥复合胶凝材料还可用于配制自流平高性能混凝上 ,在用水量为 1 80kg/m3~ 1 85kg/m3,减水剂掺量为 1 0 %~ 1 5 %时 ,其初始坍落度均在 2 0cm以上 ,坍落流动度达 58cm以上 ,且坍落度损失和坍落流动度损失均较小

The relationship between the intrinsic characteristics and the hydration properties of fly ash with high calcium oxide was studied through experiment in this research.The results show that there is low polymerization degree of silicate anions and high contents of free lime in fly ash with high calcium oxide,so it has high hydration activity,good water reducing effect,high early strength and big volume expansion in hydration.Because the crystal dimension of free lime in fly ash with high calcium oxide is smaller...

The relationship between the intrinsic characteristics and the hydration properties of fly ash with high calcium oxide was studied through experiment in this research.The results show that there is low polymerization degree of silicate anions and high contents of free lime in fly ash with high calcium oxide,so it has high hydration activity,good water reducing effect,high early strength and big volume expansion in hydration.Because the crystal dimension of free lime in fly ash with high calcium oxide is smaller and the lattice distortion is bigger,the development of expansion in hydration of this fly ash is faster.It can be developed into an effectively supplementary cementing material for cement with some appropriate technical measures.

通过实验 ,研究了高钙粉煤灰的本征性质与其水化特性间的关系 .研究结果表明 ,高钙粉煤灰由于其硅酸盐离子聚合度低 ,游离氧化钙含量高 ,因此具有水化活性好、减水效果好、早期强度发展快、水化时易产生体积膨胀等特性 .但高钙粉煤灰中游离氧化钙的晶粒较小 ,晶格畸变较大 ,因而在水泥基材料水化时产生的膨胀发展较快 .采取适当的技术措施后 ,可将其开发成一种高效的辅助性胶凝材料
