  Design Procedure for One Way Slab Here are the steps for the Design Procedure for One Way Slab in steps.For those who do not know what are the design requirements of a slab design  There are two types of slab classification based on the direction of bending occurs in these slabs.The two classifications are one-way slab and two-way slab.The basic difference between these slabs are one-way slab bends only in one direction and two-way slab bends in two directions as shown in the below figure.  Design Procedure Steps for One Way Slab 1.Based on the stiffness requirement assume suitable depth and calculate the effective span 2.Calculate the loads acting on the slab. 3.Calculate factored moment and shear force by considering the one-meter width of the slab  For simply supported slab  Factored moment =Mu= Wu× l²/ 8 Shear Force = Vu = Wu×l / 2 4.Determine the minimum depth required to resist bending moment by equating  Mu= Mulim = k×fck×bd² b=1000mm k=0.138 For F...

Compressive Strength of Concrete Cylinders The most common sample type for tests of concrete compressive strength is the concrete cylinder. There are other ways to determine concrete strength, and some methods may be more cost-effective and arguably better, but concrete cylinder testing remains the standard for acceptance. Well-made concrete cylinders are easy and inexpensive to produce. Typically, one technician posted at the point of discharge or point of placement is sufficient to sample and test concrete batches for the slump, air content, unit weight, and cylinders. Technicians must follow standard practices and be certified in most regions, but training is neither extensive nor complex. To determine the compressive strength of concrete cylinders. Apparatus  1) Compressive strength machine Procedure  1) Take out the cylindrical specimen from the curing tank.  2)Wipe out the excess water from the surface of the specimen. 3)Place the specimen vertically on the platform...

The term ‘ Setting ’ is used to describe the stiffening of the cement paste. Setting of cement refers to changes of cement paste from a fluid to rigid state. Setting differs from Hardening of cement. For concrete setting is defined as the phenomenon by which it acquire its shape as per the support inside which it is molded. It is the state from which it enters into amorphous state from plastic state. At setting state if we remove suppose it holds its position for a while but internal crack and deformation start to surface because of absence of strength The term ‘ Hardening’ refers to the gain of strength of a set cement paste, although during setting the cement paste acquires some strength. Hardening or stiffening: It happens after setting state. It is the phenomenon by which hydration of silicate compound occurs in concrete. That means it gains strength. After stiffening, in the case of removal of support it can hold its shape without crack and deformations. cement and har...
