How to check a good quality of cement at the site?

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
1: DATE OF PACKING :

When we use any type of cement for construction works so first of all
we have to check the manufacturing date of cement , Because the
cement should be used before 90 days from the date of packing .

2: RUBBING TEST :

We should get the punch of cement with finger and the cement should
be rubbing between the finger, so that time the cement should be feel smooth.

3: FLOAT TEST :

For float test we have to put some amount of cement in the glass or
other box, so the cement should be float for sometime before its sitting
.
4: TEMPERATURE TEST

Temperature test we can find very easily , first we pick some cement
from the cement bag . so that cement should give us cool feeling than
it will be the good cement.
Simply insert your hand into the cement bag, it should give cool feeling
if its quality is good. Otherwise, you may feel warm because of
hydration reaction.

5: STRENGTH TEST

Prepare a cement block of 25 mm x 25 mm and 200 mm in length.
Now submerge it in water for 7 days. Now place it on supports 15 cm
apart and load it with 34 kg weight. Block made from good cement will
not show any signs of failure.

6: CHECK FOR LUMP TEST

The lumps should be not present in the cement . and the lumps can
come in the cement due to absorption of climate.

7: COLOR OF CEMENT

The cement color should be uniform gray color with with greenish

shad.

What is Slump Test of Concrete-Cone Test Procedure | Workability of Concrete

Slump Test of Concrete-Cone Test Procedure | Workability of Concrete Slump test procedure is to determine the workability of concrete. One of the major problems that you had faced in your field work is concrete compaction during mixing.After mix design, you may have doubt, is this design will be ok? Yes, your design willl be ok in terms of strenght point of view of concrete.But the main problem arises when the mixing of fresh concrete, the compaction of fresh concrete will be very tough.In this situation, you can add some plasticizers without affecting your water-cement ratio or cement-aggregate ratio. Before adding plasticizers or superplasticizers to your fresh concrete, you need to check the workability of your concrete.The slump test is used for checking the workability of concrete.Let us check how can we do slump test of fresh concrete. Apparatus used for cone test procedure 1)Measuring scale 2)Tamping rod 3)Base plate 4)Nonporous base plate 5)Mould for slump test. ...

WHAT ARE THE DESIGN PROCEDURES FOR A BUILDING FOUNDATION?

DESIGN PROCEDURES FOR A BUILDING FOUNDATION 1. DECIDE THE LOCATION OF COLUMNS & FOUNDATION AND TYPE OF LOADS ACTING ON THEM.(E.X DEAL LOAD, LIVE LOAD OR WIND LOAD) 2. ESTIMATE ALLOWABLE BEARING PRESSURE OF SOIL USING GROUND INVESTIGATION REPORT. 3. DECIDE DEPTH OF FOUNDATION 4. CALCULATE FOUNDATION AREA 5. DETERMINE VARIATION IN VERTICAL STRESSES 6. CALCULATE SETTLEMENT 7. COST CONTROL 8. CONSIDER TIME 9. VARIATION IN GROUND CONDITION 1. DECIDE THE LOCATION OF COLUMNS & FOUNDATION AND TYPE OF LOADS ACTING ON THEM.(E.X DEAL LOAD, LIVE LOAD OR WIND LOAD) On the building plan, the position of columns and load bearing walls should be marked, and any other induced loading and bending moments. The loads should be classified into dead, imposed and wind loading, giving the appropriate partial safety factors for these loads. 2. ESTIMATE ALLOWABLE BEARING PRESSURE OF SOIL USING GROUND INVESTIGATION REPORT. From a study of the site ground investigation (if available), th...

What’s the difference between m20 and c20 grade concrete?

A concrete of Grade C20 means that the concrete will have a compression resistance of 20 N/mm² per square millimeter in 28 days. Proportion for grade C20. C20 is 1:2:4 (1 part cement, 2 parts fine aggregate, and 4 parts coarse aggregate.) where as C20 symbolizes a Cylindrical sample in which cement, fine aggregates, coarse aggregates are mixed in such a ratio that its characteristic compressive strength is 20 N/mm² after 28 days of curing. Fig:- Concrete specimen for testing Generally Strength of Cylinder sample= 0.8 x Strength of Cube. example:- M20 is equivalent to C25 M20 means the grade of concrete is defined as the minimum strength of concrete after 28 days. For the M20 Grade of concrete, The letter ‘M’ refers to the mix, and 20 represents the characteristic strength of concrete in MPa or N/mm². The specified characteristic strength of concrete is determined for 150mm size cube at 28 days. The Characteristic Compressive strength of concrete is defined as the strength of conc...

Different methods of road construction in civil engineering

Different methods of road construction in civil engineering 1) Concrete: It is a common option for road construction purposes as they are a solid material and can be used for building walls and local roads. This method is considerably less prone to wear and tear defects like rutting, cracking, stripping loss of texture, and potholes. This is the main reason for its wide usage. 2) Asphalt: This method of construction replacing concrete method in these days. They are very durable, water-resistant and can go more longer then the concrete. The major advantage of asphalt over concrete is its price. Concrete is very expensive as compared to asphalt. Moreover, asphalt includes low noise during pavement and it is easy to handle it for repairing and maintenance. That is why it is widely accepted and used by the people for the purpose of pavement surfacing. 3) Composite: This method is widely used for the maintenance, recycling, and rehabilitation of the roads. The composite m...

#4 Basic Factors Why Concentrate Cracks?

WHAT IS CONCRETE : Concrete is a building material which made from mixture of cement , sand ,crush or gravel and water. and we poured this mixture in the form work which can give us the different shapes of element like stone which is too mush strong. WHY CONCRETE CRACKS : 1: Excess of water in concrete 2: Improper Compaction of concrete 3: Rapid drying of concrete 4: Temperature Variation 1: EXCESS OF WATER IN CONCRETE Concrete does not required much water to get maximum strength . we required limit water in concrete to achieve the maximum strength of concrete . when we increase the water in concrete so it can lose the strength , so therefore concrete can crack. water is just reducing in concrete to make workabality of concrete . so increasing of water can reduce the strength of concrete. 2: IMPROPER COMPACTION OF CONCRETE before placing concrete we have to proper compact the soil. and after that when we placed concrete so concrete should be compacted properly . when the con...

What Is Splicing of Reinforcement Bars?,Rebar Formula and Brief Example

What Is Splicing of Reinforcement Bars? 🏷Splicing of reinforcement bars, commonly known as rebars, refers to the process of connecting two or more rebars in a reinforced concrete structure to ensure a continuous and load-resistant structure. 🚧It is a critical practice in construction to transfer the stresses from one bar to another effectively, maintaining structural integrity. 💫Methods of Splicing Reinforcement Bars There are three primary methods of splicing reinforcement bars: ❇️1. Lap Splice A lap splice is the most widely used method in reinforced concrete structures. In this technique, two rebars are overlapped and tied together using binding wires. The overlap length, also known as the lap length, is crucial for ensuring the splice’s strength. ⏺It is determined based on factors such as: • The diameter of the rebars. • The grade of concrete. • The specific application of the structure. ▶️The lap splice is easy to implement and cost-effective but may require additional con...
