The effect of the combined use of nanomodifiers and steel fiber on the properties of concrete

The article provides literature data on the use of various types of fiber and their effect on the performance properties of concrete. The work investigated the effect of the combined use of the nanomodifying additive TAUNIT-M, superplasticizer SP-3 and steel fiber MIXARM with a diameter of 1 mm and a length of up to 54 mm. The dependence of the strength characteristics of concrete on the amount of injected steel fiber has been established. An improvement in the intensity of concrete strength gain in the early stages of hardening has been established, depending on the complex nanomodifying additive being introduced
