1、采用防水劑補(bǔ)償收縮砼建造60m以上鋼筋砼結(jié)構(gòu)，可不留后澆帶，以膨脹加強(qiáng)帶代替后澆帶，連續(xù)澆灌砼。可解決后澆縫的清理與鑿毛給施工帶來麻煩；解決后澆縫須在60天后澆筑、工期長、滲漏隱患多的弊病。
Shrinkage-compensating concrete using repellent reinforced concrete structure built over 60m, with a time to stay after pouring to swell with the band instead of strengthening poured continuousl poured concrete. After pouring solve the seam construction cleaning and cutting hair to cause trouble; After pouring seam must be resolved within 60 days after pouring, long duration, leakage risks many ills.
2、防水劑的硫鋁酸鈣膨脹劑組份具有補(bǔ)償砼收縮達(dá)到抗裂之功效；砼在水中養(yǎng)護(hù)14天限制膨脹率≥0.015%，而一般防水劑只能抗?jié)B，不能抗裂；
Sulphoaluminate expansive component waterproofing agent has to compensate the effect of concrete shrinkage cracking reached; concrete in water conservation 14 days limit expansion ≥ 0.015%, while the general impermeability waterproofing agent can not crack;
3、防水劑高效減水劑組份具有降低砼水膠比，增加砼的和易性和密實(shí)度，進(jìn)一步減少砼收縮率，填補(bǔ)砼內(nèi)部孔隙率，達(dá)到提高抗?jié)B等級和抗壓強(qiáng)度的作用；
Waterproofing agent superplasticizer concrete component with lower water-cement ratio, increasing the density of concrete workability and to further reduce shrinkage of concrete to fill the internal porosity of the concrete, to enhance the role of impermeability grade and compressive strength;
4、防水劑隨施工季節(jié)不同，復(fù)合的緩凝劑等組份，具有降低砼水化熱，減少溫差裂縫，從而澆筑大體積砼、暑期施工砼，或摻早強(qiáng)劑或抗凍劑可澆筑冬季早強(qiáng)抗凍抗裂砼。
Waterproofing agents with different construction season, retarder and other composite components, with lower heat of hydration of concrete, reducing the temperature difference between the cracks, thus pouring mass concrete, concrete construction summer, or mixed with antifreeze early strength agent can be poured or early winter strong frost cracking concrete.
