【摘要】 研制的HF高强灌浆料具有早强、高强、耐久性好等特点,使灌浆料具有较强的锚固能力。1d即可达到后期锚固力的90%以上。良好的流动性使浆料可自动填充缝隙,灌浆层自流平稳,无须振动密实。更多还原

【Abstract】 The new developed HF high-performance grouting stuffing has such properties as high early strength,high-strength and durability so as to provide grouting with relatively great anchoring strength. And by using it,it takes only one day to get over 90 % of the entire anchoring strength.Its excellent fluidity renders the grouting stuffing the ability to fill the cracks spontaneously,smooth self-flow of the grouting layer,and the compaction degree without vibration.更多还原
