Controllable low-strength material
The invention relates to the technical field of building materials, and discloses a controllable low-strength material which comprises the following components: cohesive soil; a filler; a curing agent; solidifying the drainage agent; plant fibers; the mass of water accounts for 30%-50% of the total mass of solid substances, the controllable low-strength material prepared by taking the engineering residue soil as a raw material can be used as a controllable low-strength material of a cast-in-place underground pile (wall), and the fluidity, the strength and the solidification time can meet the cast-in-place construction requirements. After underwater pouring, the consolidation drainage agent can enable the pouring material to drain water in time in the solidification process, the solidification time of the pouring material is shortened, and the uniformity and strength formation of the material are guaranteed; the plant fibers are added, so that the cohesiveness of the material is improved on the premise that the fluidity is not changed, and the problems of loosening, falling, loss, cracking and the like of the material caused by the action of underground water are avoided.
本发明涉及建筑材料技术领域，公开了一种可控性低强度材料，包括以下的组分：粘性土；填料；固化剂；固结排水剂；植物纤维；水的质量为固体物质总质量的30％‑50％，本发明由工程渣土为原料，制备所得的可控性低强度材料，可用于灌注式地下桩(墙)的可控性低强度材料，流动性、强度和凝固时间均能满足灌注施工需要。在水下灌注后，固结排水剂可使灌注材料在凝固过程中及时将水排出，加快灌注材料凝固时间，保证材料均匀性和强度形成；加入了植物纤维，在流动性不变的前提下提升了材料的粘结性，避免了因地下水作用导致的材料松散脱落、损失、开裂等问题。
