Epoxy crack injection for concrete (the basics)jbors
Epoxy injection offers a permanent repair for cracks (and delaminations) in concrete. The repair is structural, permanent and water-tight with the same lifespan as the surrounding concrete. It can be performed at temperatures as low 35°F, on cracks as narrow as 5 mils (5/1000”) and even underwater.
The cured epoxy restores the monolithic integrity of the concrete, protects the internal reinforcing steel from corrosion and is unaffected by water, chemicals and sunlight. University studies confirm that the repaired concrete matches the original strength of the uncracked concrete. A useful performance specification for the epoxy adhesive is ASTM C881, Type IV for load bearing (structural) applications. The cured high modulus epoxy generally exhibits more than 3 times the compressive strength and over 10 times the tensile strength of the surrounding concrete.
Typical structures repaired using epoxy injection include: parking decks, stadiums, concrete framed buildings, residential foundations, swimming pools, airport runways and taxiways, concrete bridge decks, floor cracking and delaminations in warehouses and manufacturing facilities, concrete pipe and tanks, concrete beams and piers and port facilities including docks, piers and pilings. Facilities where crack injection is often employed include water/sewage treatment plants, industrial sites, machinery foundations, and refrigerated and frozen food storage warehouses.
Specially trained contractors should be considered to properly perform crack repair using proper surface preparation procedures and positive displacement metering pumps to properly proportion and deliver the two component epoxy.
Benefits of Epoxy Injection
• Fast cure strength — up to 5,000 psi compressive yield in less than 5 hours,
• Vibration tolerant during cure — repairs can be made while structure is open,
• Unique concrete crack injection solutions for underwater, corrosive, large void (low exotherm) and other extreme exposures,
• O VOC concrete crack repair adhesives and seals,
• Can be used in temperatures as low as 35°F,
• Restores cracked concrete and structural members including beams and columns to original monolithic strength,
• Stops water leakage through foundations,
• Prevents corrosion of embedded reinforcing steel,
• Useful in secondary containment areas to prevent leaks and
• Unlike urethane chemical grouts, the epoxy crack repair is structural and permanent.

This technical seminar provides basic information about the various types of cracks in concrete and their potential effect on the long-term performance of concrete structures.
Post-tensioning is a method of reinforcing (strengthening) concrete or other materials with high-strength steel strands or bars, typically referred to as tendons. Post-tensioning applications include office and apartment buildings, parking structures, slabs-on-ground, bridges, sports stadiums, rock and soil anchors, and water-tanks.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Durability in Soil
The durability of metal pipe in soil is a function
of several interacting parameters including soil
resistivity, acidity (pH), moisture content
(aeration). However, all of the corrosion
processes involve the flow of current from
one location to another (a corrosion cell).
Thus the higher the resistivity, the greater
the durability. Table on follow is lists typical
ranges of resistivity values for the primary
soil types.
Table 4 :Typical soil resistivity
Table 5 : Corrosiveness of Soils
- Durability in Water
There is little difference in the durability of
steel in still natural waters in the pH range of
4.5 to 9.5, because the corrosion products
maintain a pH of 9.5 at the steel surface.
Increasing levels of dissolved oxygen and
carbon dioxide can accelerate corrosion.
The most important effect of carbon dioxide
in water relates to its interference with the
formation of the protective calcium
carbonate scale. Dissolved salts can
increase durability by decreasing oxygen
solubility and neutralizing acidity.
to using polymer coating because it’s
environmentally friendly and also has been
tested can add life time to 10 years or
approval equivalent.
ECONOMICAL, QUICK AND EASY
- Resistance to Abrasion
The potential for metal loss in the invert of a
drainage structure due to abrasive flows is
often overlooked by designers and its effects
are often mistaken for corrosion. Three
factors must combine to caused invert
abrasion :
• Abrasive Bed load • Sufficient velocity to
carry the bed load • Flow duration and
frequency
- Additional Coating
Galvanized Z610 / EN ISO 1461 Galvanized
Z610 / EN ISO 1461 is a hot-dip zing
coating that forms a superior barrier over
steel. Calcium attracted from naturally hard
water can aid in providing additional
protection as its develops mineral scale on
the pipe surface. As the zing coating
corrodes slowly over time, it galvanicaly
protects the base steel as long as any zinc
remains.
- Coating
Additional service life can be provided by
increasing the thickness of the base or with
use Polymer Coating for additional coating.
