Aloe Vera Mucilage Enhances Self-Consolidating Concrete Workability and Strength

Preprints.org · 2023

Key Findings

01Aloe vera mucilage (AVM) effectively reduced the yield stress and increased slump flow of SCC, comparable to commercial plasticizers.
02Increased AVM dosage generally led to reduced V-funnel and L-box values, indicating improved flowability.
03LC3 blended cement exhibited lower consistency and higher setting times compared to OPC.
04A 2.5% dosage of AVM showed a notable increase in compressive strength for both OPC and LC3 samples.
05OPC samples with plasticizers achieved higher compressive strength than LC3 at 7, 14, and 28 days.

Application

Design takeaway

How to apply

When designing concrete mixes, experiment with small additions of aloe vera mucilage, starting with dosages around 2.5%, and monitor workability (slump flow, V-funnel) and compressive strength development. Compare results against mixes using conventional superplasticizers.

Project actions

01When researching materials, look for natural alternatives that can perform similar functions to synthetic chemicals.
02Document the source and preparation of any natural admixtures used, as variations can affect results.

Method & Evidence

AimTo investigate the impact of aloe vera mucilage as a bio-superplasticizer on the performance characteristics of self-consolidating concrete (SCC) made with ordinary Portland cement (OPC) and limestone calcined clay (LC3) blended cement.

MethodExperimental

ProcedureSCC mixtures were prepared using OPC and LC3 blended cement with varying dosages of aloe vera mucilage (AVM) as a superplasticizer. The performance was evaluated by measuring consistency, slump flow, V-funnel flow time, L-box blocking ratio, and compressive strength at different curing ages.

Limitations

The availability and consistency of natural materials can be a challenge. The exact chemical composition of aloe vera mucilage might vary, affecting its performance.

Reliability & validity

The study's validity is supported by systematic testing of multiple performance indicators. Reliability could be enhanced by repeating tests with multiple samples for each condition and by characterizing the AVM used.

Think critically

How might the natural variability of aloe vera mucilage affect the predictability and reliability of concrete performance in large-scale construction projects?
