Embodiment 1

[0057] Taking the aeolian sand in the Mu Us Desert as an example, the aeolian sand in the Mu Us Desert is selected for construction mortar configuration.

[0058] This kind of construction mortar prepared from desert aeolian sand is configured according to the following proportions:

[0059] Aeolian sand 290: cement 72: fly ash 20: water reducing agent 1.4: air-entraining agent 0.3: expansion agent 8: water 62: water glass 1;

[0060]The water glass is measured by volume, and the unit is liter, and the other ingredients are all measured by weight, and the unit is kilogram.

[0061] Wherein the proportion of water is the minimum value, that is, the required amount of water is not less than the proportion of water 62.

[0062] Such as figure 1 As shown, the configuration method of the construction mortar prepared by desert aeolian sand is carried out according to the following steps:

[0063] In step s1, the selection of aeolian sand is carried out: by selecting the aeolian s...

Embodiment 2

[0080] Embodiment 2: as figure 1 , 2 As shown, the ratio and process of configuring mortar in embodiment 2 are the same as in embodiment 1, the difference is: for the purpose of obtaining materials on the spot and saving costs, the local desert aeolian sand and the general cement produced locally are selected, and according to the The selected cement uses suitable additives, and the construction mortar suitable for construction can be prepared according to the process and proportion.

[0081] At the same time, natural river sand is a non-renewable resource formed in a long geological age. With the expansion of construction scale, natural high-quality sand resources will become increasingly scarce. The use of desert aeolian sand instead of ordinary river sand to prepare mortar can not only shorten the construction period, but also largely avoid the phenomenon of illegally digging rivers and destroying land to take sand, so as to protect the safety of rivers and protect the en...

Abstract

The invention relates to the technical field of building mortar engineering, in particular to building mortar prepared by using desert Aeolian sand and a preparation method thereof. The building mortar prepared by using the desert Aeolian sand is prepared by using 290kg of Aeolian sand, 72kg of cement, 20kg of fly ash, 1.4kg of water reducing agents, 0.3kg of air entraining agent, 8kg of expanding agents, 62kg of water and 1L of soluble glass through the steps of material selection, blending of dry materials, blending of liquids and preparation of mortar, wherein the soluble glass is measuredin volume, and the unit is liter; and the other materials are measured in weight, and the unit is kilogram. The building mortar prepared by using the desert Aeolian sand and the preparation method thereof have the advantages that the cost performance is higher than that of common river sand; and long-distance transportation is avoided, and thus the construction period is shortened greatly. The invention has great environmental protection significance and important theoretical and practical significance.

Description

technical field [0001] The invention relates to the technical field of building mortar engineering, and relates to a building mortar prepared by using desert aeolian sand and a configuration method. Background technique [0002] Natural sand is a non-renewable resource formed in a long geological age. With the expansion of construction scale, natural high-quality sand resources will become increasingly scarce. At present, in many places in our country, the phenomenon of digging rivers illegally and destroying land to take sand has appeared, which endangers the safety of river courses and damages the environment. [0003] With the increasing investment in petroleum engineering construction in desert areas, engineering construction requires a large amount of raw materials such as sand and stone, but the procurement and transportation of engineering sand is often expensive. Desert aeolian sand belongs to fine sand. At present, there is no systematic application standard in my...
