Do You Know How to Maintain Concrete? Solving Critical Challenges in Production, Handling, and Long-Term Integrity

1. PAIN-POINT DRIVEN OPENING

Are you losing up to 12% in annual material yield due to improper concrete handling and curing practices?
Is unplanned downtime from equipment corrosion or mixer buildup costing your plant $18,000+ per month in lost production?
Are field crews reporting inconsistent slump retention, leading to rework and delayed pours?

If you’re asking, “Do you know how to maintain concrete?” — you're not alone. Across ready-mix operations and construction sites, the real cost of poor concrete maintenance isn't just structural failure — it's operational inefficiency, compliance risk, and shrinking margins.

Consider these common challenges:

• Inadequate slump control resulting in 5–7% material waste per batch
• Residual buildup in mixers and chutes, increasing cleaning time by 35 minutes per shift
• Premature hydration during transit due to temperature fluctuations
• Surface defects in precast from improper curing environments
• Increased cement factor usage to compensate for inconsistent performance

The question isn’t just “Do you know how to maintain concrete?” — it’s whether your current methods are scalable, cost-controlled, and aligned with engineered performance standards.

2. PRODUCT OVERVIEW

The CMC-300 Concrete Integrity Management System is an industrial-grade solution designed specifically for continuous monitoring, conditioning, and preservation of fresh and early-age concrete across batching, transport, placement, and curing phases.

Engineered for integration into ready-mix plants, precast yards, and large-scale pour sites, the CMC-300 automates key maintenance functions that are typically manual or inconsistently applied.

Operational Workflow:

1. Real-time slump and temperature monitoring via embedded sensors at discharge
2. Automated water/cement ratio adjustment using closed-loop dispensing
3. Transit-time hydration control through chemical dosing (retarder/accelerator)
4. Post-placement environmental tracking (humidity, ambient temp)
5. Data logging and compliance reporting for QA/QC audits

Application Scope:

• Ready-mix truck fleets (up to 50 vehicles)
• Centralized batch plants with ≥150 yd³/day output
• Precast facilities requiring tight tolerances on curing cycles

Limitations:

• Not intended for post-hardened structural repair
• Requires integration with existing PLC or fleet telematics system
• Designed for use with conventional portland cement mixes; limited support for geopolymer systems without calibration

6. APPLICATION SCENARIOS

Ready-Mix Fleet Operation – Southwest U.S. Contractor

Challenge: High ambient temperatures (>105°F) caused premature stiffening in transit; average slump loss of 2.8” over one hour led to frequent rejections at job sites
Solution: Installed CMC-300 on eight front-discharge mixers with automated retarder dosing triggered by GPS proximity alerts within urban zones
Results: Slump loss reduced to average of 0.7”; load acceptance rose from 79% to 97%; estimated annual savings of $193k in avoided waste and fuel re-runs

Precast Concrete Manufacturer – Midwest Facility

8. FAQ

Q: Can the CMC-300 integrate with our existing batch plant software?
A:** Yes — the system supports OPC-UA protocol compatibility with major platforms including BatchTrak®, Command Alkon®, GCP Applied Technologies’ Insight®, and custom SCADA environments.

Q: Does this system replace the need for field technicians checking slump manually?
A:** It reduces dependency but does not eliminate required ASTM C143 testing at point of placement. The system provides predictive guidance but final verification remains a QA requirement.

Q: What kind of training is required for operators?
A:** Average training time is under four hours per driver/mixer operator using provided video modules and quick-reference guides. Most users achieve proficiency after three live batches.

Q: Is there a minimum fleet size needed for viable ROI?
A:** Field analysis shows positive ROI begins at approximately six active mixer units operating ≥five days/week with average round-trip durations exceeding one hour.

Q: How often do sensors require recalibration?
A:** Factory-calibrated sensors have a recommended recalibration interval of every six months under normal operating conditions; automated self-diagnostics flag drift before performance impact occurs.

Q: Are there tax incentives or depreciation benefits available? Section? A:** Equipment qualifies under IRS Code Section §179 as eligible industrial process control technology — consult your accountant regarding full expensing eligibility up front.
