Description

Изобретение относится к составам сырьевых смесей, которые могут найти применение в качестве вяжущих строительных материалов.The invention relates to compositions of raw mixtures that may find application as cementitious building materials.

Известна сырьевая смесь (вяжущее) следующего состава, мас.%: глиноземистая добавка 3,0-10,0; сульфатосодержащая добавка 0,5-9,0; портландцемент - остальное [1].Known raw material mixture (binder) of the following composition, wt.%: Alumina additive 3.0-10.0; sulfate-containing additive of 0.5-9.0; Portland cement - the rest [1].

Задачей изобретения является повышение прочности изделий, получаемых с применением сырьевой смеси.The objective of the invention is to increase the strength of products obtained using a raw mix.

Технический результат достигается тем, что сырьевая смесь, содержащая сульфатосодержащую добавку, портландцемент, в качестве сульфатосодержащей добавки включает сульфат магния и дополнительно - магнезит и флогопит, при следующем соотношении компонентов, мас.%: сульфат магния 0,3-0,8; магнезит 8,0-15,0; флогопит 3,0-6,0; портландцемент - остальное.The technical result is achieved in that the raw mixture containing a sulfate-containing additive, Portland cement, as a sulfate-containing additive includes magnesium sulfate and additionally - magnesite and phlogopite, in the following ratio, wt.%: Magnesium sulfate 0.3-0.8; magnesite 8.0-15.0; phlogopite 3.0-6.0; Portland cement - the rest.

В таблице приведены составы смеси.The table shows the composition of the mixture.

Figure 00000001

Магнезит и флогопит предварительно измельчают до удельной поверхности 3000-4000 см2/г. Компоненты дозируют в требуемых количествах и смешивают. Полученную смесь затворяют водой, взятой в количестве 45-60% от массы смеси, тщательно перемешивают, укладывают в смазанные маслом металлические формы, уплотняют и оставляют до затвердевания. Готовые изделия извлекают из форм. Прочность на сжатие полученных изделий (в возрасте 28 сут) составит не менее 30 МПа. Сырьевая смесь может быть использована в качестве вяжущего в составе бетонных смесей, включающих мелкий и крупный заполнитель.Magnesite and phlogopite are pre-crushed to a specific surface of 3000-4000 cm 2 / g. The components are metered in the required amounts and mixed. The resulting mixture was shut with water, taken in an amount of 45-60% by weight of the mixture, mixed thoroughly, placed in metal-oiled metal molds, compacted and left to solidify. Finished products are removed from the molds. The compressive strength of the obtained products (at the age of 28 days) will be at least 30 MPa. The raw mix can be used as a binder in concrete mixes, including fine and coarse aggregate.
