ICRI CSRT Grade 1 study plan

Explain how plastic shrinkage, drying shrinkage, and thermal gradients each produce a distinct cracking pattern, and sketch each pattern from memory

Identify the electrochemical mechanism of chloride-induced reinforcement corrosion and list the three conditions required for active corrosion

Classify ten written field descriptions of deterioration (scaling, spalling, delamination, efflorescence, alkali-silica reaction, freeze-thaw damage) into the correct mechanism category

Match carbonation, sulfate attack, and aggregate reactivity to their typical exposure conditions and visual indicators

Describe how a substrate survey informs the choice of removal method for at least three deterioration scenarios

Compare hydrodemolition, abrasive blasting, scarification, milling, and hand tools on removal depth control, substrate disturbance, and production rate

Determine when saw-cut boundaries and square-edge preparation are required before removal begins

Specify the correct surface profile and cleanliness standard for a given repair material and exposure condition

Sequence the steps for preparing and protecting reinforcing steel, including undercutting behind exposed bars

Identify three preparation errors that later cause disbondment or placement defects and state the inspection check that catches each

Evaluate substrate moisture, roughness, and soundness requirements against a given repair material datasheet

Explain how bond coats and primers work and state the time window between application and placement

Distinguish cementitious, epoxy, and polyurethane repair mortars by shrinkage behavior, modulus, and suitable application thickness

Select a repair material for overhead, vertical, and horizontal placements and justify each choice on placement and curing grounds

Identify compatibility risks when a stiff repair material is placed against a flexible substrate

Describe how mix water content, aggregate grading, and admixtures affect repair mortar shrinkage and strength gain

Explain the purpose and correct use of bonding agents, corrosion inhibitors, and shrinkage-compensating components

Sequence formwork erection, mixing, placement, and consolidation for a formed vertical repair

Apply placement limits on lift thickness and working time for trowel-applied and sprayed repair mortars

State the curing requirements for cementitious and polymer-modified repairs and explain what happens when curing is neglected

Differentiate dry-mix and wet-mix shotcrete placement and state where each is appropriate for repair work

Explain how to place repair material behind exposed reinforcement without leaving voids

Describe crack repair by injection and by routing and sealing, and select between them by crack width and activity

Explain the purpose of cathodic protection, chloride extraction, and surface sealers as mitigation rather than structural repair

List three placement defects (voids, cold joints, sagging) and the placement control that prevents each

Perform and interpret a tap test and a chain drag survey, and state the acceptance criteria for delamination

Explain how to verify repair depth and bond using a pull-off test, including test frequency and failure modes

Interpret slump, air content, and compressive strength test results against specification limits

Describe how to record ambient and substrate temperature and when temperature limits stop placement

Identify the documentation required to close out a repair, including inspection records and nonconformance reports

Identify the hazards of silica dust, cement burns, and abrasive blasting and state the control for each

Explain waste classification and disposal requirements for chloride-contaminated and lead-containing demolition debris

Describe containment and runoff control measures for surface preparation near waterways

List the contents of a repair specification and a pre-job safety briefing

Explain how inspection records support warranty claims and dispute resolution

Complete a full-length timed practice exam and score each domain separately

Review every missed question and trace it to the underlying principle rather than memorizing the answer

Re-drill the two weakest domains using the decision tables and matrices built in earlier weeks

Summarize the ten facts most likely to be tested and state each in one sentence

Confirm readiness by meeting a target score on a second timed attempt
