Lightweight Cement Composition for Reduced Bag Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The weight and volume of traditional cement bags cause storage and transportation inefficiencies and worker fatigue due to their heavy weight, leading to stress-related injuries and increased energy consumption.
Innovation Solution
A lightweight cement composition comprising Portland or hydraulic cement, hydrous magnesium silicate, sodium tall oil, sodium stearate, sodium C14-16 Alpha Olefin, and silicon dioxide, which reduces the bag weight to approximately 65 pounds while maintaining the same volume of mixed product as traditional cement mixes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional cement bags weighing 78-80 pounds are used, then the strength and consistency of mortar and stucco are maintained, but worker fatigue and stress-related injuries increase due to the heavy weight
Solution Approach 1:
The patent changes the physical-chemical parameters of the cement composition by incorporating specific additives (hydrous magnesium silicate, sodium tall oil, sodium stearate, sodium C14-16 Alpha Olefin, linear alkyl benzene, and silicon dioxide) that modify the density and mixing characteristics of the cement, allowing it to achieve the required strength and consistency at a lower weight of 65 pounds per bag
Solution Approach 2:
The patent creates a composite cement material by combining traditional cement with multiple functional additives that work together to reduce weight while maintaining or enhancing performance characteristics, resulting in a lighter but equally effective cement composition
2Strength
If traditional cement bags with larger volume are used, then the strength requirements are met, but storage space and transportation fuel consumption increase
Solution Approach 1:
The patent modifies the volumetric parameters of the cement bag by adjusting the composition to achieve higher density or more efficient packing, reducing the volume occupied by each 65-pound bag while maintaining the strength properties required for mortar and stucco applications
Solution Approach 2:
The patent creates a simplified version of traditional cement that achieves the same functional output (strength and consistency in mortar/stucco) with reduced volume and weight, effectively providing a more efficient copy of the traditional product
3Strength
If more cement bags are transported to meet project requirements, then the strength and consistency needs are satisfied, but transportation costs and energy consumption increase
Solution Approach 1:
By changing the weight parameter of the cement bag to 65 pounds while maintaining strength properties, the patent reduces the total weight that needs to be transported, directly lowering fuel consumption and transportation energy requirements for delivering the same volume of mixed product
