Embodiment 1

[0031] The mortar provided in this embodiment is preferably used as a material for the construction of the agitating pile machine, and the mortar can reach the strength grade of C5-C15 after solidification. The mortar has gelled slurry and particles mixed in the gelled slurry, the density of the gelled slurry is greater than the density of water and less than or equal to the density of the particles.

[0032] Among them, the particles are mixed in the gelled slurry and at least a part of the particles are suspended in the gelled slurry. In order to ensure that the particles can be stabilized in the suspended liquid gel without settling or a small part slowly settles to ensure the composition of the mortar stability, the density value of the gelled slurry is close to the density value of the particulate matter.

[0033] In the embodiment, the particulate matter is one or a combination of river sand, pulverized coal particles, mineral powder particles, ceramsite, construction wa...

Embodiment 2

[0041] In this embodiment, for the same parts as those in Embodiment 1, the same text descriptions are omitted.

[0042] Compared with Example 1, in the mortar provided in this example, the cementitious slurry includes suspension and cement, and according to the different performance levels of the suspension, the weight ratio of the suspension and cement is 3:10 to 5:1, and The weight ratio of the suspension to the cement is preferably 1:2 to 5:1; the weight ratio of the suspension to the cement is preferably 1:1 to 3:1, and the weight ratio of the suspension to the cement is more preferably 1 :1~1.3:1.

[0043] Table I

[0044]

[0045]As shown in Table 1, when the weight of cement is constant, increasing the weight of mud can also increase the weight of river sand correspondingly. The higher the weight of river sand, the higher the strength of the mortar after solidification, and because The lower overall cement specific gravity results in lower mortar material costs. ...

Abstract

The invention discloses mortar. The mortar comprises gelatinized slurry and particles mixed in the gelatinized slurry, the density value of the gelling slurry is greater than the density value of water and less than or equal to the density value of the particulate matters; at least part of the particles suspend in the gelling slurry; pipe blockage or instability of mortar components caused by rapid sedimentation of particles in transportation operation can be prevented; the maximum particle size of the particles is smaller than the minimum inner diameter of the mortar conveying pipeline; the cementitious material with viscosity can wrap and uniformly adhere the particles serving as the aggregate, the cementitious slurry can improve the fluidity of the particles in the mortar conveying pipeline, and the mortar conveying smoothness can ensure that the construction operation of the mixing pile machine is continuous, efficient and fault-free; the abrasion of particles to the mortar conveying pipeline can be reduced, and the service life of the mortar conveying pipeline is prolonged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a mortar. Background technique [0002] Mixing pile is a soft soil foundation treatment method, using cement mortar as the main agent of the curing agent, using a mixing pile machine to spray the curing agent slurry into the soil and fully stirring, so that a series of physical and chemical reactions between the curing agent and the soil occur. Harden soft soil and improve foundation strength. The conventional mixing pile sprays a curing agent, such as cement or cement slurry, at the same time of stirring, so that the curing agent and the soil are mixed and then solidified into a cement-soil mixing pile under the action of the curing agent, which improves the strength of the soil in the mixing area and achieves the purpose of retaining soil. , The role of water stop. [0003] However, due to the lack of aggregate, the strength of the mixing pile made by spraying or s...
