A nonlinear particle packing model for micro-aggregate

Zhihua Sun et al.

Summary: The non-linear packing model for micro-aggregate was developed based on the non-linear packing model for granular soil to predict the actual packing density. The characteristics, differences, and applications of five common packing density calculation models were discussed. The correlation coefficients of the particle packing model based on granular soil were adjusted to establish the packing density relationship for micro-aggregates. The derived relationship was validated with an average relative error of less than 0.4% and a root mean square error within 3.2 x 10-3.

Derivation and verification of multilevel particle packing model for Ultra-High Performance Concrete (UHPC): Modelling and experiments

Tianyi Yin et al.

Summary: This paper proposes a new multilevel particle packing model for the precise design of ultra-high performance concrete (UHPC) by deriving the modified Anderson and Andreasen (MAA) equation. The dense packing states of powder and aggregate segments are achieved, and the accurate ratio of two segments are confirmed, leading to the calculation of the optimal mix proportion of UHPC matrix. In addition, some novel viewpoints on the development of dense particle packing theory are presented, which could further improve the design theory of UHPC composites.

Influence of the fine aggregate particle packing effects on the paste rheological thresholds of self-compacting concrete

Miao Lv et al.

Summary: This study proposed a new method to calculate the paste threshold, which can more accurately describe the influence of fine aggregate particle packing on the threshold. The accuracy of the modified calculation formula was verified by comparing the self-compacting paste zones and self-compacting concrete zones. The results showed that the modified threshold calculation method had higher accuracy in predicting self-compacting performance.

Development of Cold-Bonded Briquettes Using By-Product-Based Ettringite Binder from Ladle Slag

Ahmed Abdelrahim et al.

Summary: This paper introduces a more sustainable method for recycling steel plant side streams through cold-bonded briquettes. A binder based on ettringite is used as a replacement for Portland cement, and its mechanical and thermal properties are assessed. The results show that briquettes produced with a higher content of ettringite-based binder exhibit excellent mechanical properties and a better swelling behavior under conditions simulating a blast furnace.

Properties and microstructure of packing-optimised recycled aggregate concrete with different cement paste or sand contents

Yuan Jiang et al.

Summary: The study found that increasing CPV leads to a higher slump in RAC due to increased lubrication effect, while increasing Bs decreases slump due to reduced paste film thickness. Higher CPV reduces macroporosity and improves strength, but excessive CPV weakens properties. Proper Bs enhances particle packing and properties, but too much sand can increase porosity and degrade mechanical properties. Flexural strength of RAC is minimally affected by CPV or Bs.

Reconnoitring principles and practice of Modified Andreasen and Andersen particle packing theory to augment Engineered cementitious composite

S. Indhumathi et al.

Summary: The study focuses on optimizing the mixture proportions of Engineered Cementitious Composites (ECC) using the Modified Andreasen and Andersen (MAA) theory, which reduces the number of trial mixes by incorporating the particle packing concept. The results show that the optimal dosage of High Range Water Reducing Admixture (HRWRA) is 2.62% with a water binder content of 0.16, and the 09 mix recipe exhibits improved compressive strength at 28 days.

Rational design of lightweight cementitious composites with reinforced mechanical property and thermal insulation: Particle packing, hot pressing method, and microstructural mechanisms

Luansu Wei et al.

Summary: The study focused on the preparation of a novel lightweight cementitious composite (HP-LWCC) using the hot-pressing method and optimizing the insulating particles packing. Results showed that HP-LWCC specimens with density of 800-1200 kg/m3 exhibited superior mechanical properties and thermal insulation. The optimized particles packing of HP-LWCC decreased the porosity of specimens and improved the strength, providing a potential solution for thermal insulated construction applications.

Development and Evaluation of Nano-Silica Sustainable Concrete

Habib H. Alqamish et al.

Summary: The study indicates that adding nano-silica to concrete can significantly improve the compressive strength of mixtures containing 30% GGBS, but its impact on mixtures containing 70% GGBS is less predictable. Additionally, nano-silica can enhance the microstructure and interface structure of the mixtures.

Flexural performance of reinforced concrete beams made by using recycled block aggregates and fibers

Wadhah M. Tawfeeq et al.

Summary: This study analyzes the influence of using GBFS, RBA, and different types of fibers on the flexural performance of reinforced concrete beams. The experimental results showed that these substitute materials had an impact on the compressive strength and flexural tensile strength of concrete to some extent. However, using these substitute materials in certain proportions can enhance the flexural capacity of reinforced concrete beams.
