Description

Известные способы подбора состава бетона предусматривают проведение предварительных испытаний заполнителей с определением их удельного веса, чистоты, пустотности и т. д., или проведение пробных затворений с изменением дозировок материалов . Такие способы очень трудоемки и не дают хороших результатов .Known methods of selection of the composition of concrete include conducting preliminary tests of aggregates with the determination of their specific gravity, purity, voidness, etc., or conducting test gates with changing the dosages of materials. Such methods are very laborious and do not give good results.

Дл  устранени  этих недостатков предлагаетс  предварительно подбирать раствор с заданным водоцементным отношением и с заданной пластичностью , а дальнейшее изготовление бетонной смеси осуществл ть добавлением крупного заполнител  к раствору при встр хивании до получени  смеси требуемой подвижности илн жесткости.To eliminate these drawbacks, it is proposed to pre-select a solution with a given water-cement ratio and with a given plasticity, and further manufacturing the concrete mix is carried out by adding a coarse aggregate to the solution with shaking until a mixture of the desired mobility or stiffness is obtained.

Пор док подбора состава бетона заключаетс  в следуюи1.ем.The procedure for selecting a concrete composition is as follows.

Обычным путем определ етс  водопементное отношение. Затем приготавливаетс  раствор с пластичностью в 204-25 см расплыва на встр хиваюш,ем столике. При этом к сухой смеси постепенно добавл етс  вода, а затем, по мере разжижени , добавл етс  песок. Таким путем происходит вы в. физических и геометрических особеиностей песка и иасьииение их цементного теста, что обеспечивает оптимальное соотношение иемента, песка и воды как в растворе, так и в бетоне.The water exchange ratio is determined in the usual way. Then a solution is prepared with a plasticity of 204-25 cm spreading on a shaking table. At the same time, water is gradually added to the dry mixture, and then, as it is thinned, sand is added. In this way you are in. physical and geometric features of sand and its cement paste dyeing, which ensures an optimal ratio of cement, sand and water both in mortar and in concrete.

Когда раствор приготовлен, определ ют объемный вес и выход раствора . Затем беретс  навеска крупного заполнител  (грави , щебн ) н к нему добавл етс  раствор в количестве на 10% большем объема пустот заполнител . После персмеии вани  определ етс  удобоукладываемость смеси. В случае неудовлетворительной удобоукладываемости добавл етс  раствор пории ми по от ранее вз того количества. После этого может быть определен объемный вес приготовленного бетона и расход материалов.When the solution is prepared, the volumetric weight and the yield of the solution are determined. Then a sample of coarse aggregate is taken (gravel, rubble) and a solution is added to it in an amount 10% larger than the volume of the voids in the aggregate. After persistence, the workability of the mixture is determined. In case of unsatisfactory workability, the solution is added at a porous amount of a previously taken amount. After this, the volume weight of the prepared concrete and the consumption of materials can be determined.
