Abstract:

The article presents a study of innovative materials in the field of highly mobile and cast concrete mixtures using pipeline transport. The studies were carried out on mixtures with a complex additive based on S-3 superplasticizer. The complex included a plasticizing-air-entraining additive LHD with an air-entraining effect. Studies of the effects of S-3 and LHD additives on the construction and technical properties were carried out on mixtures with different cement flow rates and the same initial mobility. Studies of the rheological parameters of the mixtures were carried out using the mathem

The paper presents studies to establish the regularity of the influence of the number of sections of the distribution mast in the upper position on the fuel consumption of the concrete pump when idling. The number of sections of the distribution mast of the concrete pump in the upper position complicates the pumping of cement mortar to the place of pouring concrete structures. The loss of the pressure of the pumped solution is compensated by an increase in engine speed, which leads to an increase in hourly fuel consumption.

Presently constructors use peristaltic concrete pumps for wet shotcreting processes or for transferring the building mixes to the place of their deposit. Fitting the flexible-hose concrete pump with a hydraulic drive allows both making the range of its operating modes much broader and enhancing its reliability. Numerically simulated models of the building mixes feeding processes were developed to design a hydraulic drive to fit the general-service flexible-hose concrete pump and to calculate its basic parameters.

Loads subjected by the boom system on the concrete pump are so complex, that fatigue cracks or fatigue fractures appear, which may lead to loss of property and casualty. However, when the concrete pump is functioning in safe condition, the damage of the boom system is reduced, thereby preventing the accidents. In order to select safe working conditions, a boom system of 37m concrete pump as research object should be adopted. The finite element analysis is carried out on the boom system based on MSC.

Abstract:

The nonconstant concrete flow due to the alternating pumping of the twin cylinder of the hydraulic pump will cause vibration of concrete pump trucks. Furthermore, the discontinuous pumping of concrete caused by inadequate suction and air doping will exacerbate the vibration. In order to study the effect of nonconstant and discontinuous pumping of concrete on the dynamic response and vibrational stability of the whole vehicle, multi-fluid pumping models with concrete-lubrication gas for straight and elbow pipes are established, respectively, and the boundary conditions of periodic pumping speed

Abstract It was attempted to provoke and foresee sudden loss of workability during concrete pumping through a series of full-scale tests. Batches of 2 m3 concrete were produced at a ready-mix plant, transported by concrete trucks and pumped by industrial pumps, to reveal sudden loss of workability. Different mix designs, extension hoses and pump setups were utilised in a six series experiment. An experimental procedure for measuring loss of workability at a laboratory scale was developed due to the standardised procedures for slump measurements camouflaging loss of workability.

This paper represents a first attempt to study the feasibility of using shear wave (SW) ultrasonic probes as pump-wave sources in concrete microcrack detection and monitoring by Nonlinear Ultrasonic Coda Wave Interferometry (NCWI). The premise behind our study is that the nonlinear elastic hysteretic behavior at microcracks may depend on their orientation with respect to the stationary wave-field induced by the pump-wave source. In this context, the use of a SW probe as a pump-wave source may induce the nonlinear elastic behavior of microcracks oriented in directions not typically detected by

A deficiency in accurate and current regulations, along with a lack of experience in sanitary construction, makes the installation of sewers challenging. Using models, it was determined that if the pumps were operated simultaneously, the service would last for a long time over the entire sewer system. With a daily sewage inflow of 468 dm3, the system was found to run 14.4–14.7% longer than expected at 100 pumping stations. Each month, the pressure-sensitive sewer system receives more than 51 min of extended service from the city’s central sewer system. Increasing wastewater inflow and the numb
