High-fluidity high-strength foundation pile self-balancing static load test pile post-grouting body formula
The invention relates to a grouting body formula, in particular to a foundation pile self-balancing static load test pile post-grouting body formula, and belongs to the field of building materials. The high-fluidity high-strength foundation pile self-balancing static load test pile post-grouting body formula comprises, by weight, 40-70% of cement, 0-25% of fly ash, 0-15% of silica fume, 0-1% of awater reducing agent, 0-8% of an expanding agent, and 15-40% of water, wherein the sum of the weight percentages of the components is 100%. The high-fluidity high-strength foundation pile self-balancing static load test pile post-grouting body formula has the following advantages: 1, the compression resistance and the bending resistance are good; 2, the self-flowing state, the high flowability andthe high self-compactness are realized; 3, micro-expansion is realized; 4, the homogeneity is good, the material homogeneity is good, the upper part and the lower part of the slurry are not separated, and the bleeding rate is low; 5, the construction is easy; 6, the flowing property is well maintained, and the flowing property of the slurry meets the construction grouting requirement within the initial setting time; and 7, the flowing property is well maintained, and the loss of the flowing property of the slurry is small as time goes on.
本发明涉及一种注浆体配方，尤其是一种用于基桩自平衡静载试桩后的注浆体配方，属于建筑材料领域。一种高流动性高强度基桩自平衡静载试桩后注浆体配方，按照重量百分比，其组分包括水泥40％‑70％、粉煤灰0‑25％、硅灰0‑15％、减水剂0‑1％、膨胀剂0‑8％、水15％‑40％；且各组分的重量百分比总和为100％。本发明具有如下优点：1、抗压、抗折性能好；2、自流态，高流动性和高自密实性；3、微膨胀；4、匀质性好，材料的匀质性良好，浆体上、下不产生离析，泌水率低；5、易施工；6、流动性能保持好，在初凝时间内浆体流动性能能满足施工注浆要求；7、流动性能保持好，随着时间增加，浆体流动性能损失性小。
