Filler materials are gaining widespread popularity and becoming very important because they help in increasing some of the mix properties and also lower the usage of binder which is usually more expensive
Here is the table showing some common filler materials along with binders

CONTINUOUS BEAMS AND ONE-WAY SLABS

The ACI Code gives approximate formulas for finding shear and bending moments in continuous beams and one way slabs. A summary list of these formulas follows. They are equally applicable to USCS and SI units. Refer to the ACI Code for specific applications of these formulas.

For Positive Moment

End spans

If discontinues end is unrestrained wl ² _n / 11

If discontinues end is integral with the support wl ² _n / 14

Interior spans wl ² _n / 16

For Negative Moment

Negative moment at exterior face of first interior support

Two spans wl ² _n / 9

More spans wl ² _n / 10

Negative moment at other faces of interior supports wl ² _n / 11

Negative moment at face of all supports for slabs with spans not exceeding 10ft (3m) and (b) beams and girders where the ratio of sum of column stiffness to beam stiffness exceeds 8 at each end of the span wl ² _n / 12

Negative moment at interior faces of exterior supports, for members built integrally with their supports

Where the support is a spandrel beam or grider wl ² _n / 24

Where the support is a column wl ² _n / 16

Shear Forces

Shear in end members at first interior support 1.15 wl _n / 2

Shear at all other supports wl _n / 2

End Reactions

Reactions to a supporting beam, column, or wall are obtained as the sum of shear forces acting on both sides of the support.

American Society for Testing and Materials (ASTM) specifications cover renforcing steel. The most important proper- ties of reinforcing steel are

1. Modulus of elasticity E _s , lb/in ² (MPa)

2. Tensile strength, lb/in ² (MPa)

3. Yield point stress f _y , lb/in ² (MPa)

4. Steel grade designation (yield strength)

5. Size or diameter of the bar or wire

The tensile strength of concrete is used in combined-stress design. In normal-weight, normal-density concrete the tensile strength can be found from
___
f _r = 7.5Ö f ^’ _c lb / in ² in USCS units
___
f _r = 0.7Ö f ^’ _c MPa in SI units

The modulus of elasticity of concrete E _c adopted in modified form by the ACI Code can be calculated by the formula given below:
