Estimation of geopolymer concrete strength from ultrasonic pulse velocity (UPV) using high power pulser

Journal of Building Engineering, 2018
Abstract The objective of this paper is to establish the relationship between the ultrasonic pulse velocity (UPV) and the compressive strength of geopolymer concrete. The specimens used in the studies were geopolymer concrete synthesized at ambient temperature with alkali activators of different concentrations.

Investigation of the effects of aggregate textural properties on compressive strength (CS) and ultrasonic pulse velocity (UPV) of concrete

Journal of Building Engineering, 2020
Abstract Aggregate is the most volume covering component in concrete. The strength and durability properties of the aggregate can affect the hardened and fresh concrete properties. Apart from the strength and durability properties, the textural properties of the aggregate can also affect the hardened concrete properties. In this study, the effects of

Homogeneity of papercrete with 10% waste paper substitution using Ultrasonic Pulse Velocity (UPV)

AIP Conference Proceedings, 2021
Paper waste production in DKI Jakarta according to data from The Jakarta’s Environmental Services reaches an average of 40% of total waste production per month for each municipality (kotamadya). On the other hand, Indonesia’s necessity of construction development, notably residential home, is increasing constantly along with the amount of Indonesia’s ...

Correlation Between Ultrasonic Pulse Velocity (UPV) and Compressive Strength of Coal Bottom Ash Mortar

Journal of The Institution of Engineers (India): Series A, 2021
The utilization of coal bottom ash (CBA) as natural sand replacement in mortar is a feasible solution to reduce the environmental issues created due to its disposal. However, strength behavior of CBA mortar varies from conventional natural sand mortar.

Non-Destructive Means of Predicting Masonry Prism Strength Using Ultrasonic Pulse Velocity (UPV)

2023
Current ASTM standards call for grouted masonry prisms to be tested for compressive strength at 28-days to ensure compliance with the structural design. In the event of failing tests, the subject samples may require redesign or reconstruction which can pose problems due to ongoing development around and including the prisms between the time of ...

Ultrasonic pulse velocity (UPV) and initial rate of water absorption (IRA) of foam concrete containing blended cement

Materials Research Proceedings, 2023
Abstract. The adverse environmental effects caused by cement production activities could be minimized by reducing the use of cement in the concrete mix, replacement with eco-friendly materials, and making low-unit weight cement-derived products. During the cement production activities, fly ash can also be used by mixing it in form of Portland Composite
