烧料礓石拌合遗址土浆液结石体室内试验研究
Laboratory study on properties of calcined ginger nuts mixed with earthen sites' soil for grouting materials
摘要
Abstract
With the aim of finding theoretical basis for applying calcined ginger nuts to earthen sites, the calcined ginger nuts was used to reinforce earthen site of Xiaguanying as the grouting materials. The physical and water properties of the calcined ginger nuts were tested. The results show that after mixing calcined ginger nuts, the silt particle contents increases, while the clay particle contents decreases and the sand particle contents doesn't change basically in calculus body, and the structure is more dense and water loss rate is slower compared with that of the calculus body mixed silicon. Calculus body has little shrinking and deforming capacity, which increases liquid and plastic limit, and improves the plasticity of soil. The calculus body is of small permeability and strong resistance to disintegration ability. The internal components of calcined ginger nuts react with the soil particles and water so that the physical and water properties of the solidified form change to some degree. The sample has good structural stability, integrity and water resistance. Therefore, it can be used as excellent grouting materials for earthen sites. The test results can provide the basis for the performance of calcined ginger nuts to reinforcement of earthen sites and the preferred ratio should be chosen on the basis of cracks case.关键词
