wall materials: concrete and brick. Similar wall modeling has been reported in the literature [1] but by using a different approach. Several measurement techniques used to characterize the typical building materials such as brick, concrete, glass, plasterboard, plywood, wood etc. in terms of the frequency dependent dielectric

Simulation of Motion Behavior of Concrete in Pump Pipe by DEM

May 26, 2021 · The pumping pressure of concrete with pumping speed of 0.71 m/s in horizontal pipe, bend pipe, and vertical pipe increased by 0.0074 MPa, 0.0888 MPa, and 0.0264 MPa, respectively. The pumping pressure of concrete in the horizontal pipe was converted into pressure loss per meter (MPa/m), as shown in Table 7. <- Prev.

Assessment and prediction of concrete flow and pumping

Feb 19, 2019 · Up to10%cash back · Relative humidity plays a critical role in concrete creep. To accurately measure and model creep behavior of concrete considering the relative humidity effect is difficult despite more than 100 years of research of concrete creep. In this study, a test set-up was designed to measure the creep-induced deflection of concrete beams exposed to different drying …

What is Viscosity, and Why is Measuring Viscosity Important?

Petroleum: Viscosity measurements project the effectiveness of lubricating oil and determines design elements of pipelines. Concrete: Viscosity determines the self-leveling and pumping behavior of a mix. Cosmetics: Viscosity should be considered when designing the feel and flow of cosmetic products.

Steel–Concrete Composite Beams Considering Shear Slip

Sep 27, 2001 · The present study investigated the effects of shear slip on the deformation of steel–concrete composite beams. The equivalent rigidity of composite beams considering three different loading types was first derived based on equilibrium and curvature compatibility, from which a general formula to account for slip effects was then developed.

Prediction on pipe flow of pumped concrete based on shear

Oct 01, 2013 · The concrete pump was a high pressure piston pump (model BSA2110HP-D, Putzmeister Co., Germany). Three different flow rates were studied as shown in Table 2. The filling rate of the pump cylinder, which directly affects the flow rate, was calibrated from specific experiments prior to the real concrete pumping.

Concrete Slump Test for Workability -Procedure and Results

The slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests since 1922. The slump is carried out as per procedures mentioned in ASTM C143 in the United States, IS: 1199 – …

Pump Terms and Definitions

Classification by Specific Speed. Specific Speed (n s) - Specific speed is an index of pump performance at the pump's best efficiency point (BEP) rate of flow, with the maximum diameter impeller, and at a given rotative speed. Specific speed is used for many design purposes including efficiency prediction and classifying the relative discharge of an impeller as radial, mixed or axial and

Frontiers | Measurement, Prediction, and Control of

A prediction is dependent on the model parameters previously identified in approximation on different data sets (i.e., approximation is performed on training data and prediction on test data). In short term prediction, we are interested in predicting HR responses to the change of load based on current input data over a certain time horizon.
