Preparation and properties of lightweight and high-strength building ceramsites with oil-based drilling cuttings pyrolysis residues

Frontiers in Materials, Journal Year: 2023, Volume and Issue: 10

Published: Aug. 24, 2023

With the continuing advancement in China’s exploration and development technologies of shale gas resources, there was a significant increase oil-based drilling cuttings. In this paper, cutting pyrolysis residues (ODCPRs) used as main raw material for preparing lightweight high-strength building ceramsites to eliminate environmental risks recycle industrial waste. Firstly, orthogonal experiments were study influences composition, preheating temperature, time, sintering time on properties ceramsites. From results, temperature content ODCPRs discovered be key factors affecting process Secondly, heating rate ceramists further explored find optimum conditions. When ceramsite set 50%, obtained presented excellent with particle compressive strength 6.31 MPa, bulk density 575.11 kg/m 3 , apparent 1097.24 water absorption 1.89%. Finally, XRD, SEM, TG-DSC, heavy metal leaching comprehensively conducted analyze composition structure variation mechanism ceramsite. This paper presents an approach recycling, utilization, disposal cuttings oil field waste management.

Development of red mud based sintered artificial aggregates with various industrial wastes

Materials Research Express, Journal Year: 2024, Volume and Issue: 11(6), P. 066401 - 066401

Published: May 22, 2024

Abstract Red mud (RM) has drawn a lot of attention in the search for potential uses production sintered artificial aggregate from industrial waste products. The main objective study is to produce an RM-based (SAA), with several blends (binary, ternary, and quaternary) using various wastes. This includes assessing mechanical physical properties SAA as well sintering parameters order determine appropriate material mix ratio. To achieve these objectives, comprehensive experimental approach was adopted. A total 35 different mixtures were formulated by incorporating wastes binders additives. green pellets preheated at 105 °C 24 h, consecutively temperatures, namely 700 °C, 900 1100 1150 duration 30 min. compressive strength test performed find property similarly water absorption bulk density tests conducted SAA. characterize SAA, scanning electron microscope analysis (SEM), X-ray diffraction (XRD) energy dispersive x-ray conducted, also data Artificial Neural Network (ANN) tools, yielding accurate predictions. Successfully best low produced. weight ratio identified (A18) RM: Fly Ash: Waste Glass Powder; 78:10:12. Out all ternary blend exhibited impressive after min °C: high 22.92 MPa, 4.26%, 1296.12 kg m −13 . made possible amount Al 2 O 3 , SiO combination fly ash, glass powder RM. SEM XRD confirmed that achieved strength, due turning surface core area into solid, reduced internal pores formed quartz, hematite phases. findings this serve foundation future work pave way development sustainable construction materials.
