Basalt Brick Storage Tank Resisting Sulfuric Acid Corrosion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage tank designs for sulfuric compounds using steel-reinforced concrete are prone to corrosion and structural failure due to the degradation of concrete and steel reinforcement by sulfuric compounds, especially under extreme temperature variations.
Innovation Solution
A storage tank constructed with basalt bricks and calcium silicate grout, which are non-porous and resistant to thermal expansion, eliminating the need for steel reinforcement and preventing sulfuric compound ingress, thereby maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel-reinforced concrete is used for storage tank construction, then structural strength is improved, but corrosion resistance to sulfuric compounds deteriorates
Solution Approach 1:
The invention removes steel reinforcement from the concrete structure, eliminating the component that is most susceptible to corrosion by sulfuric compounds. The tank is constructed using only concrete without any metal reinforcement, thereby preventing corrosion-related structural failure while maintaining necessary strength through proper concrete formulation and design.
Solution Approach 2:
The invention uses a composite material system consisting of concrete with specific composition (including cement, aggregates, and chemical admixtures) that provides both structural strength and chemical resistance. The concrete is formulated with specific water-cement ratios and supplementary cementitious materials to achieve both mechanical properties and resistance to sulfuric acid penetration.
2Ease of manufacture
If conventional concrete is used for storage tank construction, then ease of manufacture is improved, but durability under extreme temperature variations deteriorates
Solution Approach 1:
The invention modifies the chemical and physical parameters of the concrete to enhance its performance. This includes using specific water-cement ratios, incorporating supplementary cementitious materials, and adjusting aggregate composition to improve thermal stability and resistance to temperature cycling while maintaining workability during construction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The basalt-brick and calcium silicate grout storage tank design prevents corrosion and structural failure, ensuring long-term storage of sulfuric compounds without degradation, even under extreme temperature conditions.
Implementation Method 1
The plurality of bricks are arranged to define a floor, a plurality of walls and a roof of a storage tank to contain sulfuric compounds. The roof curves upwardly between each of the lateral walls thereby facilitating the roof to support a load without reinforcement.
Implementation Method 2
each of the bricks can resist ingress of sulfuric compounds into the bricks... the grout is comprised of calcium silicate to resist the ingress of sulfuric compounds into the grout
