新型抗震灌浆加固材料的技术研究

因现役石砌体灰缝砂浆饱满度低，抗震性能差，石粉对环境又有不良影响，提出以石粉为集料配制浆体，对石砌体灌浆加固。经试验和研究，该材料施工方便、经济合理、效果好，灌浆石砌体抗剪强度高，是寓环保与抗震防灾为一体的新型灌浆材料，具有较好的研究和应用价值。

The Technological Study of New Type Grouting Material for Anti - Seismic Reinforcement

To counter the low plumpness of mortar joints in active service stone structure and the characteristic of its poor seismic behavior, and also the harmful effect to environment stone powder , the stone powder cement mortar which takes stone powder as forestry logging and the grouting reinforcement to stone structure is presented in this paper. After tests and study ,the material makes clear that the constructional method is convenient and inexpensive but benefit ,the grouting effect is marked and it is good in shear-resistant strength of grouting stone structure .It is one kind of new type grouting material with environmental protection and earthquake-resistant and taking precautions against natural calamity .It is quite good in the value of study and application .
