GREEN BUILDING & STABILIZED EARTH BLOCK MAKING COURSE OUTLINE

Course Overview

The Green Building & Compressed Stabilized Earth Block (CSEB) Making Course at the Zebra Liquid Vocational Institute is a 1-month intensive vocational program. This course provides practical skills in sustainable construction using soil, minimal cement or lime stabilizers, and manual press technology to produce eco-friendly, energy-efficient building blocks. CSEB technology eliminates wood-fired brick burning, preventing deforestation and greenhouse gas emissions while delivering durable, low-cost structural walls.

Combining soil testing, block production, wall masonry, and construction business skills, this course equips participants to start block-making enterprises or work on green construction sites. Trainees receive post-training mentorship and certification assistance.

Course Objectives

By the end of the course, participants will:

• Conduct field soil testing (ribbon, drop, and sedimentation tests) to identify suitable construction soils.

• Calculate precise stabilizer mix ratios (lime, cement, bio-binders) for varying soil compositions.

• Operate manual and motorized hydraulic earth block presses to produce uniform structural CSEBs.

• Master block curing protocols, quality testing, and dry-stack masonry techniques.

• Establish a green block manufacturing enterprise, price products competitively, and meet building standards.

Course Structure and Topics

Week 1: Soil Mechanics and Soil Testing Techniques

• Introduction to Green Building: Environmental advantages of earth architecture vs. fired clay bricks.

• Soil Composition: Understanding clay, silt, sand, and gravel ratios required for structural blocks.

• Field Soil Testing: Sedimentation bottle tests, jar tests, drop tests, and shrink tests.

• Soil Preparation: Excavation, sieving, drying, and crushing soil to uniform grain sizes.

• Hands-On Practice: Conducting field soil tests on local soil samples and sieving raw earth for block production.

Week 2: Mix Design, Press Operation, and Block Production

• Stabilizers & Additives: Using 5–8% cement, lime, or agricultural ash to stabilize earth.

• Moisture Control: Calculating and testing optimum moisture content (OMC) using the hand-squeeze test.

• Press Machine Operation: Operating manual lever presses (e.g., Cinva-Ram) and block presses.

• Production Workflows: Mixing, mould filling, compaction, ejection, and initial handling of green blocks.

• Hands-On Practice: Batching soil mixes, operating a manual CSEB press, and producing interlocking structural blocks.

Week 3: Curing, Quality Control, and Green Masonry

• Curing Protocols: Moisture retention, plastic covering, watering schedules, and 28-day strength development.

• Quality & Strength Testing: Measuring block dimensions, drop durability, water absorption, and crushing strength.

• Interlocking Masonry: Laying interlocking CSEBs, thin-bed mortar application, and corner alignment.

• Plastering & Rendering: Formulating breathable earthen renders, lime washes, and waterproof natural seals.

• Hands-On Practice: Curing block stacks, conducting drop-break tests, and building a sample interlocking wall section.

Week 4: Business Management, Costing, and Market Linkages

• Production Economics: Calculating raw soil, stabilizer, labor, and machine depreciation costs per block.

• Eco-Marketing & Sales: Positioning CSEBs to eco-lodges, housing developers, schools, and homeowners.

• Standards Compliance: Aligning production with national building codes and UNBS quality standards.

• Business Planning: Developing a commercial yard layout, equipment acquisition plan, and labor workflow.

• Hands-On Practice: Creating a full financial cost sheet for a block yard and presenting a business proposal.

Training Approach

• Trainer-Learner Ratio: 1 trainer per 30 learners (with dedicated assistants for safety monitoring).

• 80% Practical Learning: Most of the day is spent on the production site.

• Follow-Up Support:

  • 6 months of mentorship for workshop setup and technical troubleshooting.

  • Assistance in sourcing reliable equipment and affordable raw materials.

  • Connections to local construction firms and industrial hubs.

Assessment and Certification

Participants will be assessed through:

1. Practical Test: Testing on Block Production Quality after producing certified high-strength CSEB samples 

2. Yard Operation: Completion of a production yard operation plan.

3. Graduates will receive a Certificate of Competency from Zebra Liquid Vocational Institute, with pathways for DIT/Trade Test certification.

Community Impact and Market Access

By training local youth and entrepreneurs, we reduce the community's reliance on imported bricks and construction materials and create high-earning local jobs. Graduates gain access to the VSLA program for startup toolkits to launch their own businesses.
