SMH General Construction (@ethioengineers1) Amxar til segmentidagi kanali faol ishtirokchi. Hozirda hamjamiyat 23 384 obunachidan iborat bo'lib, Uy & Arkhitektura toifasida 424-o'rinni va Efiopiya mintaqasida 1 450-o'rinni egallagan.
đ Auditoriya koârsatkichlari va dinamika
новŃдОПО sanasidan buyon loyiha tez oâsib, 23 384 obunachiga ega boâldi.
31 Iyul, 2026 dagi oxirgi maâlumotlarga koâra kanal barqaror faollikka ega. Oxirgi 30 kunda obunachilar soni -289 ga, soânggi 24 soatda esa -7 ga oâzgardi va umumiy qamrov yuqori darajada qolmoqda.
- Tasdiqlash holati: Tasdiqlanmagan
- Jalb etish (ER): Auditoriya oârtacha 20.12% darajada jalb etiladi. Nashrdan keyingi dastlabki 24 soatda kontent odatda umumiy obunachilar sonining 6.54% ini tashkil etuvchi reaksiyalarni toâplaydi.
- Post qamrovi: Har bir post oârtacha 4 705 marta koâriladi; birinchi sutkada odatda 1 530 ta koârish yigâiladi.
- Reaksiyalar va oâzaro taâsir: Auditoriya faol: har bir postga oârtacha 20 ta reaksiya keladi.

Yuqori yangilanish chastotasi (oxirgi maâlumot 01 Avgust, 2026 da olingan) sababli kanal doimo dolzarb va katta qamrovli boâlib qoladi. Analitika auditoriya kontent bilan faol hamkorlik qilishini, uni Uy & Arkhitektura toifasidagi muhim taâsir nuqtasiga aylantirishini koârsatadi.
Important Notes For Civil Engineering Student
âQ1: What does 1:2:3 concrete mix mean?
â
Answer:
It means 1 part cement : 2 parts sand : 3 parts coarse aggregate by volume.
â Q2: What is the strength of 1:2:3 concrete?
â
Answer:
Approx. 20 MPa (N/mm²) at 28 days
Equivalent to M20 grade concrete
â Q3: What is the formula to calculate compressive strength?
â
Answer:
fck = P/A
fck= compressive strength
P= failure load (N)
A = loaded area (mm²)
â Q4: What is the ideal water-cement ratio for 1:2:3 mix?
â
Answer:
đ Typically 0.45 â 0.60
Lower ratio = higher strength
Higher ratio = lower strength
â Q5: How much strength is gained in 7 days?
â
Answer:
đ About 65%â70% of 28-day strength
â Q6: What are the common uses of 1:2:3 concrete?
â
Answer:
â Slabs
â Beams
â Columns
â Footings
â General RCC work
â Q7: How to calculate material quantity for 1 mÂł concrete?
â
Answer (Approx):
Cement = 6â7 bags (â 300â350 kg)
Sand = 0.44 mÂł
Aggregate = 0.88 mÂł
đ Based on dry volume factor â 1.54
â Q8: Why actual strength differs from theoretical strength?
â
Answer:
Because of:
Poor mixing
Improper curing
Excess water
Low-quality materials
Lack of compaction
â Q9: What happens if water is too much?
â
Answer:
â Reduces strength
â Causes cracks
â Increases porosity
â Q10: What is the curing time required?
â
Answer:
đ Minimum 7 days (normal)
đ Best practice 14â28 days
â Q11: Is 1:2:3 mix still recommended?
â
Answer:
đ For small works âď¸
đ For major structures â (Use design mix)
â Q12: What test is used to check strength?
â
Answer:
â Cube Test (150Ă150Ă150 mm)
â Cylinder Test
