Pomacea canaliculata Shell Waste Enhances Compressed Earth Brick Strength by 104.90 kN

Scientific Reports · 2025

Key Findings

01The optimal compressive strength of 104.90 kN was achieved with 25% shell waste replacement, surpassing the Thai Industrial Standard for non-load-bearing bricks.
02Peak density was observed at 50% shell waste replacement (2434.5 kg/m³), with water absorption ranging from 16.05% to 17.43%.
03FEA confirmed structural stability and efficient stress distribution in a double-walled system constructed from these bricks.
04The shell waste, rich in calcium carbonate, reacts with soil components to form calcium–silicate–hydrate (C–S–H) gel, enhancing material strength.

Application

Design takeaway

How to apply

Investigate local agricultural or industrial waste streams for potential use as supplementary cementitious materials or aggregates in construction projects, focusing on performance enhancement and environmental benefits.

Project actions

01When selecting waste materials, consider their chemical composition and potential for binding or reinforcing properties.
02Ensure thorough testing of mechanical properties to meet or exceed relevant industry standards.

Method & Evidence

AimTo investigate the mechanical properties and structural stability of compressed earth bricks (CEBs) incorporating varying percentages of Pomacea canaliculata shell waste as a partial cement replacement.

MethodExperimental and Simulation-based Research

ProcedureCompressed earth bricks were fabricated with a 1:5 cement-to-soil ratio, substituting cement with 0%, 25%, 50%, 75%, and 100% Pomacea canaliculata shell waste. Mechanical properties including compressive strength and density were tested. Material composition was analyzed using XRD and XRF. A double-walled system constructed from these bricks was analyzed for structural stability and stress distribution using Finite Element Analysis (FEA) software.

Strengths & Limitations

Strengths

+Empirical testing of mechanical properties.
+Use of FEA for structural analysis.
+Addresses multiple UN SDGs.

Limitations

The availability and consistency of waste materials can vary, impacting replicability. Long-term performance and weathering effects may not be fully captured in short-term studies.

Reliability & validity

Reliability would be enhanced by repeating tests on multiple brick samples for each percentage. Validity is supported by the comparison to industry standards and the use of FEA for structural assessment.

Think critically

How might the processing of the shell waste (e.g., grinding fineness, cleaning) affect its performance in the CEBs, and what are the potential economic implications of such processing?

Design Principles

"Waste valorization through material substitution can lead to improved product performance and reduced environmental impact."

This research demonstrates a viable method for upcycling agricultural waste into a functional building material. By reducing reliance on traditional cement, it offers a pathway to lower embodied carbon in construction and mitigate the environmental impact of invasive species.

What This Means for Your Design

Adding crushed snail shells to bricks makes them stronger and better for the environment because it uses waste material and less cement.
