Concrete Testing in Madinah
Certified fresh and hardened concrete testing — pour supervision, compressive strength, core sampling, concrete durability per ASTM and SASO 1452.
Concrete testing is a set of field and laboratory tests on fresh and hardened concrete verifying compressive strength, slump, and durability before, during and after pouring. Performed by an accredited concrete testing lab per ASTM and Saudi Building Code SBC 304, it confirms ready-mix concrete meets required specifications before any pour is accepted on the project.
What Is Concrete Testing and Why Is It Essential on Every Project?
Concrete testing is a series of checks beginning the moment ready-mix concrete arrives on site and continuing up to 28 days after pouring. This includes slump measurement to verify workability, and cube sampling later tested to determine actual compressive strength. Per Saudi Building Code SBC 304, no concrete batch may be accepted without an accredited lab supervising the pour and sampling.
Concrete is the core structural material of any building — any deviation in its strength or composition can threaten the entire structure's safety. Precise on-site concrete testing catches problems before the concrete sets, while core sampling verifies existing structures' quality after construction.
As a concrete testing laboratory accredited to ISO/IEC 17025:2017 (SAAC accreditation No. N-T-00645), Asas Lab provides full field supervision of ready-mix concrete pours in Makkah, Jeddah, Madinah, Riyadh, and Qassim, issuing certified compressive strength reports accepted by consultants and government authorities across the Kingdom.

Pour supervision + temp/slump + cube sampling (7 & 28 day)
الإشراف على صب الخرسانة + هبوط + عينات مكعبات (7 و28 يوم)
Field pour supervision including slump measurement, temperature, and cube sampling tested at 7 and 28 days — the core test verifying compressive strength compliance per SBC 304.
Unit: sample
Air Content
محتوى الهواء
Measures entrained air content in fresh concrete — an important indicator of freeze-thaw resistance in concrete testing for elevated/mountain regions.
Unit: test
Unit Weight
وزن الوحدة
Determines the unit weight of fresh concrete per cubic meter — used to calculate mix quantities and verify ready-mix concrete consistency.
Unit: test
Initial & Final Setting Time
زمن الشك الابتدائي والنهائي
Measures initial and final concrete setting time — essential for planning sequential pours and curing concrete under Saudi Arabia's high temperatures.
Unit: test
Thermo Couple Test (mass concrete)
درجة حرارة الخرسانة الكتلية
Monitors mass concrete temperature during hydration to prevent thermal cracking in large structural elements such as footings and raft foundations.
Unit: test
Bleeding of Fresh Concrete
نسبة النضح
Measures the amount of mixing water rising to the surface of fresh concrete — excessive bleeding indicates a flawed concrete mix design.
Unit: test
Concrete Core Samples (with report)
كور خرساني (مع تقرير)
Extracting a cylindrical core sample from existing hardened concrete to verify actual compressive strength — used to confirm concrete quality in older buildings or disputed pours.
Unit: sample
Ferro Scan (rebar detection)
الكشف عن حديد التسليح (Ferro Scan)
Locates rebar positions and cover depth inside a concrete element non-destructively — supports structural assessment and verifies execution against design drawings.
Unit: point
Schmidt Rebound Hammer
مطرقة الارتداد شميدت
A non-destructive test estimating surface concrete strength via rebound — a fast screening tool for existing concrete before deciding on core extraction.
Unit: point
Ultrasonic Pulse Velocity (UPVT)
الموجات فوق الصوتية (UPVT)
Measures ultrasonic pulse travel time through concrete to detect internal voids and cracks and assess structural homogeneity.
Unit: test
Half Cell Potential (corrosion)
نسبة الصدأ في حديد التسليح
Assesses the probability of rebar corrosion inside concrete via electrical potential measurement — important for assessing older structures or those near marine environments.
Unit: test
Concrete Durability Package (5 tests)
حزمة ديمومة الخرسانة (5 اختبارات)
A comprehensive durability package (chloride permeability, water absorption, water penetration) determining concrete's long-term resistance to environmental factors.
Unit: sample
Concrete Testing in Madinah — Quality in the Prophet's City
Madinah's hotel towers, Prophet's Mosque expansion support infrastructure, and road networks require strict concrete quality monitoring. Local basaltic aggregate is dense with low absorption — ideal for high-performance concrete — but some basalt types contain volcanic glass minerals requiring ASR potential testing per ASTM C1293. ASAS Lab runs full QC programs: site sampling, 7- and 28-day cube testing, weekly compliance certificates, and resident technician service for large projects.
Adopted Engineering Standards
All concrete tests are performed to adopted Saudi and international standards

How Does the Concrete Testing Process Work?
From pre-pour coordination to the final compressive strength report
Pre-Pour Coordination
We receive your request and confirm the pour date, required concrete grade and design strength. We send you a quotation within 24 hours and confirm the field technician's attendance with sufficient advance notice.
Field Supervision and Sampling
The field technician attends the site before pouring, measures slump and temperature, then takes representative cube samples for each concrete batch as required by the drawings.
Curing and Laboratory Testing
Samples are cured in calibrated tanks per ISO 17025 and tested at 7 and 28 days using precision hydraulic compression presses to determine actual compressive strength.
Compressive Strength Report Delivery
You receive an engineering-certified report showing each sample's results and compliance with the design compressive strength — ready for submission to the consultant and government authorities.

FAQ About Concrete Testing
SBC 304 requires a slump test (ASTM C143) and compressive strength on cubes at 7 and 28 days (ASTM C39 / SASO 1452) per concrete batch. Infrastructure and major projects add durability requirements such as RCPT and water absorption.
