# Study on the Effects of Pasture Fiber on Thermal Properties of Slag Bricks

## TL;DR

This study explores how adding pasture fibers to slag bricks affects their thermal properties, aiming to create sustainable building materials.

## Contribution

The novelty lies in using pasture fibers as additives in slag bricks to improve thermal performance and sustainability.

## Key findings

- Increasing pasture fiber content initially reduces thermal performance before improving it.
- Lower thermal conductivity correlates with lower density and higher porosity in composite samples.
- Incorporating pasture fibers reduces waste and supports sustainable building material development.

## Abstract

In the context of ecological sustainability, this study focuses on the effect of variables of pasture fibers on the thermal properties of slag bricks made from a green recyclable material. This experiment uses slag as the binder, sand as the aggregate, and pasture fiber as an additive. The experimental variables include the additive content ratio of the pasture fiber, the size of the pasture fiber, and the type of pasture fiber. Significance analysis of the experimental results of the thermal performance tests is carried out using Minitab 18.1.0 software, and the optimal ratios for the thermal performance of the composite samples are derived from the response optimizer and conformity analysis. The results of the experiment’s test analysis using Minitab 18 software indicate that, with an increase in pasture fiber content, the thermal performance of the composite samples initially decreases before increasing. Additionally, the lower the thermal conductivity of the composite sample, the lower the apparent density and the higher the porosity. Incorporating pasture fibers into slag bricks, as revealed in this study, reduces the waste of pasture resources in pastoral areas and promotes the development of sustainable building materials with favorable thermal properties.
